heya im running a pretty cheap comp compared to a lot of you guys im just wondering if my new gpu is been bottlenecked? 
fsp blue storm psu 500 watt
asrock 939 dual vsta
1 gig ddr400 cheapo stuff
athlon 64 sandy 3700 @ 2.6 (only gained about 500/600 3d marks when i put it to that)
ocuk/triplex 1950 pro pcie 256 mb
vista ultimate
getting about 13000 on 3dmark 03 and about 8.5k on 05 does that seem normal for this rig?
gonna be doubling ram very soon and thinking of a dual core cpu although might be cheaper just to get a core 2 duo set up.
