Mobo bottlenecking gpu?

[Tore J]

Hello,
i have a msi p35 neo-f mobo with a xfx gtx 285 installed. Imo my gpu doesnt produce the fps it should in games, such as bfbc2 im around 30-50 fps on high settings and 4x aa/af. in MW2 im around 85 fps highest settings.in gta4 fps is 25-40ish on high settings.

i havent used any benchmarking tools but i dont expect the results to be much different.

my cpu q9400 is oc'ed to 3.4ghz
my ram is 4gb Corsair TWIN2X PC6400C4DHX DDR2
windows 7 64
650w psu

I dont really think my cpu,psu or ram is to blame(i hope), so im wondering if it maybe could be my mobo that doesnt quite support my gtx 285

Well, how much fps did you expect for your system?
BFBC2 and GTA4 are considered heavy games, i guess your fps is about right...
What resolution did you play at?

Its not your motherboard, even if it was running x8 instead of x16 it wouldn't make enough difference to say it was slowing your FPS.

i dont expect great fps in bfbc2 and gta4. but after reading around a bit i would assume i should have a fair bit more.

i play at a 1920x1080 resolution. but turning it down to the lowest even doesnt help much. maybe a gain of 5-10 fps, which isnt worth it. because i do run the games smooth. unless i sit and monitor my fps a see a drop and my head plays tricks on me and i swear i can see it in game

I just read something about my gtx 285 having pci-e x16 v 2.0, and after digging around a bit about my mobo i think it has pci-e x16 v1.0a. would that have any inpact on fps. and would a mobo with pci-e x16 v2.0 perform better?

i maybe should try some benchmarking tool. which is the most reliable one?
im pretty much a novice when it comes to hardware related stuff, so any help would be greatly appreciated.

edit: should also mention i got the latest beta driver 257.15 and updated bios.
