Nvidia 7900 GT in SLI or single ATI X1950XTX?

Need some advice.
I am re-building my system and would like some advice regarding which graphic card(s) to use. This rig is strictly for gaming. I have a pair of BFG 7900 GT OC cards and a single ATI X1950XTX. The 7900's are 256mb each and the 1950 has 512mb. I usually play in lower resolutions such as 1280X1024 4AA. I don't know if this is important but the monitor I use is a Dell 24" FP. Also, the card will be on an Nvidia 680i reference board.

I tried looking at the comparison charts on THG but the results were somewhat confusing. It appears the ATI card has better performance in the higher res but the Nvidia's have better performance in lower resolutions.

Which setup is going to give me the best performance with the highest FPS (I prefer speed over eye candy)?

Any advice would be greatly appreciated.

The X1950XTX is better than 2 7900GT's. I'd say go with the X1950.



Good Luck. :D

It's difficult to say as those two setups will differ greatly based on applications. In F.E.A.R., the 7900GTs would likely outperform the X1950XTX, but in Oblivion the X1950XTX would win. I'd say use the X1950XTX as you won't have to worry about SLI support and you've got the ability to use HDR+AA.

Go with the X1950XTX, play at the native resolution of your LCD, and turn up the eye-candy.

Use the X1950XTX for now. Sell the other two. Then sell the ATI card once DX10 hits full force and get you something sweet. :)

I used to have both these card setups. At 1280x1024 the 7900 GT SLI's will give you more FPS in most games (and higher min FPS in particular), Oblivion being the exception. If you go higher than that resolution, the 1950xtx will start to overtake them, due in large part to having more memory, especially in shader-heavy games.

However, you do have to deal with the extra heat and power requirements if you go SLI.

All in all, I'd say go with the 1950xtx unless you really want those extra FPS. Less headaches with a single card...

Thanks for all your replys. I will go with the X1950. I plan on upgrading to a DX10 at some point but I'm in no hurry. I want to wait and see what unfolds between Nvidia and ATI/AMD. Right now I think the 8800 GTX is way over priced and ATI hasn't come out with anything to compete with it. Lets see what happens in a few months. Thanks again for your advice.

If you have both, then you can try them both and see.

I would install the X1950XTX as well. Little less hassle setting up SLI, and will take up less space also.
