Christ thats a pretty powerful rig you have already.  The Q6600 should be beefy enough to get the best out of the game, and in all honesty unless you are going for a top end card changing the gfx card isnt going to really add that much in the way of a % boost. 

Maybe wait a few weeks for a patch or two and see how things pan out?  I had to upgrade in my case as my dual core was never gonna cut it.  Then I had to improve the card as well as the 5770 would have been a possible bottle neck.

A lot of us run games at 800x600, with custom sound and gfx settings tweaked to come out at less than the games default 'low quality settings'.

This means we can get upto a possible 80-100fps in most games like Quakeworld, Tribes and that CPU hog, Duke Nukem 3D!

technology, eh?  incredible... *shakes head in wonder*

Seriously though, at that (very nice) resolution, you will probably end up needing a couple of decent cards in SLI or similar to drive the panel at a very high FPS.

lower the resolution to 800x600 for the lol and post a screenie for us!

what resolutions does that monitor support ?

try going below the 2k horizontal res and see does in make a diff

I always feel its wrong to run a game outside the panels native resolution.  Maybe I'm wrong!

Aye, but as the max of this thing is only 1280*1024, it's not saying a lot.

Lads would one of the latest ATI cards improve things much?
While i realise the 5800 or 5900 series are a big performance boost would the Q6600 be a bottleneck?
I tried overclock the Q6600 with stock cooling and she wouldnt boot up, if needed i might get some decent cooling.

I have an i5 w/ the ATI 5870 and it runs like a dream at 1920x1200. The only thing that causes some slowdown is someone dropping a building on my head from a tank spot. At that stage, FPS doesn't really matter

Gotta love the xbox though - no need to worry about this crud all the time.

Ok have done some more testing, managed to overclock the cpu using my mobos inteli tweaker thingy, seems me being a noob changed something else in the bios lastnight which is why she wouldnt boot up.
It was very stable and no problems at all set to "turbo" not sure precisely what speed it was getting to but apparently it auto overclocks the cpu when needed.

Heres the strange bit, i swapped my highly edited settings ini out and replaced it with the origional just out of interest and straight away ingame fps were massively improved at stock cpu and gpu speeds

I guess i was reading too much into a few BC2 performance tweak guides on the net.
Im now seeing a minimum of 50 fps and max of 90,usually hovers at around the 60-70- mark even with building blowing up etc, im at medium settings @ 1650 X 1280 running set to auto  same as before but the difference is massive - oh and im running dx 10 now and shes rock solid

Lesson learned - dont always believe what so called tweak guides suggest.
