SLI necessary?

post #1 of 14
Thread Starter 
I might get another 7900GT OC for SLI but will it have negative effect because I run 1280x1024? If not, approximately how much performance in percentage would I gain?

And please no "you should get something else" suggestions.

It will not have a negative effect, if anything it will allow you to push your AA and AF to higher settings while still being able to keep an acceptable framerate. The best reason to get it imo though would be in preparation for DX10. If you cant afford a DX10 GPU, then SLI is really going to come in handy when the DX9.L games come out. Until then though, you can feel comfortable turning all games to max settings and having nice framerates!

Thought some people were actually having lowered performance with SLI on these lower resolutions.

I can have a 2nd card for free but I was just worrying about having negative effect, and since I'm getting a full tower I'd probably get another Tide Water too.

Rep+ for you.

No, the only cases where I have heard of lowered performance from SLI is in the case of two 7950GX2. The drivers for quad SLI are complete crap, and as such, at lower resolutions people were seeing a drop in FPS. With regular SLI (not quad SLI) you should see an all around increase.
post #5 of 14
in SLI v. non-SLI, i get the same performance at a low res (1024x768, 8xAA, 16xAF) with either. but i get markedly better performance at 1280x1024 (8xAA, 16xAF) w/ SLI compared to a single card. dunno if that mirrors anyone elses situation.

the only issue that i've run into is no support for multi-monitor setups in SLI mode.

You can still use it! When you want to run a game, you set SLI, one of your monitors will turn off, the other will stay on. When you are doing gaming, turn off SLI, and the monitor that was off will turn back on and be usable!

you don't always have to run in SLI-mode, just turn it back on (which needs a restart) before you game. once i get an lcd monitor i'm turning it off so i can use both my current CRT and the new one.

It just doesnt support it, I dont think it will any time soon either. There are ways you can work around it, but they are expensive.
