GeForce 8800GTX Performance
Quantum:
To be honest I highly doubt that person was running Oblivion in max settings :P. Maybe max settings at a low resolution, but not real max settings. Oblivion as it goes is quite CPU taxing as well as GPU taxing and I'm afraid there exists no pentium at all that can run Oblivion at a comfortable frames per second at near max settings.
I have a feeling the person was probabily running the pre-set "Very High" settings, which just doesn't compare to what I've seen an AMD X2, nVidia 7900GT on a 1600 x 1200 CRT monitor do, once you go and tweak everything (going in to the options menu with all the graphical settings).
If you're comparing a 6800GS to what I can only assume is a 7800GT, then I'm afraid you're somewhat mistaken in thinking they are close:
Here is a comparison of a 6800GT running GDDR3 memory (I honestly think this GT card will be much faster than your GS card) to a 7800GT:
http://www.tomshardware.co.uk/graphics/charts.html?modelx=33&model1=527&model2=540&chart=211
On Oblivion at 1600 x 1200, no AA, 8 x AF,
6800GT: 28 FPS
7800GT: 45 FPS
Throwing in the same benchmark but comparing to the 8800GTX:
8800GTX: 110.9 FPS
Also note:
2 x 7900GTX in SLi: 91FPS, still slower than the 8800GTX and only 15% faster than the single card version:
7900GTX: 79FPS
And finally to throw one more set-up in the mix 6800GT in SLi, because it is GT, I feel it will be a very high upper bound for your GS cards (unless you've managed to open all pipelines and over clock it, without any artefacts at all):
2 x 6800GT in SLi: 44 FPS

Not being a serious gamer I ask you for an opinion on this link.
I cannot understand how the FPS are so low on 6800GT(unless this is just a standard card) However using Nividea Forceware drivers on the Gainward 6800 GS GLH and the 7800GT Oblivion is quite playable. Apparently Oblivion automatically sets specs to max on setup. However Oblivion is not without faults and I await your comments.Tks
cheers

The typical rule for how powerful a GeForce graphics card is given the letters at their end (lowest power to highest power):
LE < GS < GT < GTX
I've not found an exact rule, but from my experience, the GT has lower clock speed, the GS has less pipelines opened and a lower clock speed, and the LE has even less pipelines, less clock speed and less features.
You have tools to increase clock speed and open up pipelines, but often cards are given the letters at the end because they were made to be GTXs but they were defective at certain clockspeeds or certain pipelines were broken, so you can rarely max them to a GTX level. Also there are sometimes physical constants involved in the specifications of lower graphics cards, which simply can not be over come.
The type of memory involved is a big factor as well, for such powerful things as graphics cards, latency is a big issue for graphics card as well as clock speed, a rough rule of thumb for how good memory is (but not always true actually, you need to check out the exact specifications and compare it to a benchmark program)
GDDR4* > GDDR3 > DDR3 > GDDR2** > DDR2 > DDR
* Only available on certain ATi products at the moment, it's major feature over GDDR3 is power savings, so its clock speed can be made to be much higher
** I'm not sure this is actually a formal type of memory, from my experience things which claim to be GDDR2 are simply high quality DDR2 memory.
Anyway, that tweak guide is brilliant for getting the most out of your graphics card, not only for oblivion but the start really helps for games in general.
I have a lowly 6600 card (but over clocked) and am able to play Oblivion on reasonable setting (1280 x 960 with a few nice features turned on and distance of things generally at medium), but it took quite a lot of tweaking to get that kind of performance out of it. Benchmarks are run at stock settings, don't think this is unfair because you can equally tweak for a 8800 and get much better performance out of it (there are even higher graphical settings that the benchmark hasn't used).
It's not that the game isn't playable on lower end graphics cards (6600+ and x1600+, even lower if you get a patch called oldblivion) it's just that you can't really appreciate it's beuaty without something with a bit more kick to it, and single graphics cards almost always provide a better performance gain per the amount of extra cost you are spending on them vs. dual graphics cards (twice the price, 15% - 60% extra power)

Many thanks for input Quantum. Makes more sense now. Just a small point on 6800GS GLH card, these are factory overclocked cards core485mhz mem 1300mhz, and not an ordinary GS card,they can go a bit more. At this moment I am running core 510mhz and mem 1430mhz with no problems,and have still a good bit in reserve. These cards along with the 7800 have been discontinued,but can be picked up very cheap if you know where to look ;D Your link didnt mention Gainward cards and my 6800GS is way above the 6800GT (which you are comparing it with) and more like the 7900GT which plays Oblivion with no problems.
I am extremely happy with performance and graphics and at my age wont need much more.lol
cheers

Pls see my new post on SLI Mobos. Yours and Synbios arguments are out the window. My Mobo can handlle new system but Ill wait until the 8800gtx comes down to £100 and that wont be too long.. But then something new will be out and we will all have to change our systems again .
Never ending upgrades to put more money in the coffers of Nividea/ATI and others,
Every time a new card comes out,everyone is on the bandwagon, saying this is the best thing since sliced bread.. New technology is coming out week after week. What you shout about this week will always be supersided the following week.But isnt that what discussion is all about ;D cheers
