I just bought a gtx 460 as an upgrade from a 8800GT. I have gotten way better framerates in many stress tests, but i seem to be having issues with SC2. I'll be floating around 50 fps in game and then for half a second it will drop down to like 2 FPS then pick back up. This happens a lot in replays and in games.
Also it appears that my performance is almost identical to my 8800GT in SC2, though in other games it has greatly increased. This leads me to belive that before I was playing in DirectX 9 on my 800GT, and now I am playing in DX10 with my gtx 460 by default. My question is can I force sc2 to run in DX9 as i see no point to run DX10 if i dont have to.
Thanks,
SPECS;
GTX 460 (for main 2 monitors, the one i play on) 9800GT (for 3rd monitor) Q6600 @2.4 GhZ P5N-E SLI ready motherboard 2 500GB Harddrives 4GB RAM Windows 7 32 bit

SC2 is a DX9 game and open GL not DX10 or 11
|
Starcraft II is DirectX 9 only. You don't need to force it.

Thanks guys, it would appear as if something else is causing an issue, any ideas?

First of all, your GPU doesn't really matter that much in SC2 as you can see in this benchmark:

In your case the CPU seems to be the limiting factor, that's probably why your FPS didn't improve much from your old card in SC2. I'd say 50fps seem perfectly ok for the system you're running. The issue with FPS dropping to 2fps for just a moment is annoying, I have it myself sometimes. But this usually disappears after I played my first game. I'm not sure what causes it, I have a GTX460 myself but this also happened with my old Radeon5770.

yeh q6600 is probably bottlenecking the gfx card to death

I have a 500W PSU, do you think that this is enough for this setup, also if i OC my CPU to around 2.8-3 GhZ will i notice a significant jump in performance.

500W is probably cutting it close, since you'll have 2 video cards. OC'ing will only make it worse.

The 9800 GT probably wouldn't take much more than idle power if the GTX 460 is running the game, so I think it should be quite reasonably within limits as long as the PSU can live up to its rating.

Yes you will notice an increase in performance, how big who knows. just don't OC blindly and do the proper stuff, unless you got OCGENIE ;D

Yes and Yes probably, but be careful with heat on the q6600, especially if you don't have g0 stepping

Thanks for the help so far, I double checked and its a 600W PSU, so i'm hoping that's enough. I plan on buying a new CPU fan before OC' ing, as i don't have much faith in the stock one because i've overheated with that one before and dont want to run the $300 risk of burning out my CPU.
Anyone have any suggestions if im going from 2.4 to 3.0Ghz how good of a fan i'll need, or is anything above stock good enough.

Erm, that CPU is obsolete (relatively speaking) and isn't worth anything close to $300 anymore. 300 nearly gets you an i7 these days. And obviously wasn't too great when you bought it either since they were $850+ when they first came out.

The point of the post wasn't to tell all the members of team liquid how much money I spent on my CPU when I bought it 2-3 years ago. I was simply asking about CPU fans. Rather then look for the receipt I took an educated guess on an arbitrary number which had no bearing on the question that was asked.

Those are good links by lqd - considering the keynotes, they mention that the P5N is good for 350FSB on quads - you only need 333Mhz FSB to get 3Ghz anyway. But yeah before getting started, as the keynotes emphasize, make sure your idle/load temps at stock are good before you raise voltages.
On purchasing a "CPU fan" - I believe you mean heatsink. Many heatsinks can be used for older and newer sockets, so if you are spending good money, remember that your investment should last more than an upgrade cycle. I would recommend an HDT heatsink like the CM212+...though really any HDT or traditional tower heatsink is going to be plenty for you.
