285 SSC SLi or 295 quad?

296 8
Hello, I have been having a hard time getting the information on this. I had a 720W power supply, so I thought I'd be able to run 2 285's, and not spend too much money. I had to upgrade my power supply anyway, to a Zalman HP-1000. My cards run fine now, but it would only cost about 250 cdn more to go to Quad SLi. I didn't do it in the first place, because I didn't plan on getting a new PSU. I have a Q9550 at 3.6 Ghz, and 4 gb of ram on a 780i mobo. I can play Crysis: Warhead fully on enthusiast and 4x AA at 1920 x 1200, but when the action gets too intense, it can drop to about 20fps, though it averages above 40 during most play.

Is this a CPU or GPU limitation?

Thank you for any help, I'm brand new to the forum, but I'll give rep for help.

I say wait a while before going quad SLI. There are probably going to be a lot of bugs and with such new drivers you won't get close to the same performance as you should.
Stick with what you've got for now, there's no real point upgrading.

OK to deal with the drop in frames, do exactly XFreeRollerX suggested. I wouldn't be surprised if it's your CPU that's bottle necking because you have 2 extremely fast and powerful GPUs and I doubt that any CPU wouldn't bottle neck them.
