Not entirely happy with my new rig's performance on high-end games..

I'm starting to wonder whether I'm expecting too much? I'd seriously hope not for the 1k I shelled out over the rig listed below. But the fact is, I'm not getting the kind of flawless performance I want on games such as Bioshock & even a game pretty dated now in Oblivion. So with that said, I'm pushing the boat further & am looking at upgrading on what I have below. Bare in mind this is a brand new system, what would you sugest I add to what's already there? Thanks.

Came out at 11551 marks.

Your system compared to all 2787470 system configurations. There are 169153 systems with a higher score and 2618317 systems with a lower score than your system.

When it first came out people got scores of a couple thousand. Its made to benchmark, of course its not going to run at 100 FPS, that wouldn't be benchmarkin much.

Those scores are perfectly normal and are as they should be. I am running Crysis at Very High with XP tweak and the overclockers.net FPS tweak, no AA and 1440x900 and getting 25-40 FPS. Have you tried tweaking settings and so forth?

Dunno why yours should be bad at bioshock... i only have a 8600 gts and i have it max and it runs finebigdave00

he only has a 19 inch monitor tho...
