anything overclocked?

gpu fan working ok?

try uninstalling and re-installing drivers? 

i run all my games 1680x1050, all settings maxxed, and i usually get 60fps+, sometimes 45-50FPS average

so my 2gb of ram is keeping up fine, no need for more yet..

just make sure its quality 2gb of ram, all u should be thinking about

dunno bout intel motherboards, currently cruisin with AMD.. aint gotten around to studying recent intel motherboards yet

There is no definitive way to tell if a graphics card is good or bad. It depends on your needs and your budget. There are numerous factors that can affect whether you think a graphics card is good or bad that are not shown in the technical documents.

In order to see whether a graphics card or good or bad, search for reviews on that particular card. Be sure to read numerous reviews as opinions may differ from reviewer to reviewer. After that, go with what the general consensus among the reviewers is.

well 1 thing is for sure, go for a nvidia card.. 8series (8600, 8800, etc) .. but u need PCI-E slot for them, AGP is way outdated..  

PCI-Express interface(If you have)

How much memory installed (256MB or more)

Memory Speed (1000MHz or more)

Memory Width(256 bit or more)

Stream processors(32 or more but 64 is better)

Core Speed (500 or more)

Also Pixel Shader 4 support

And somemore

he seem like he aint to knowledgeable about pc's so i dunno if he will beable to answer all that.. but what kinda slot he got (PCI-E, or AGP) would be useful.. or just tell us what motherboard u got 

an E6600 intel, or AMD 5200 X2 will both be good for games, i run all my games at 1680x1050 with all max setting and usually get 60fps+ .. so those 2 processors are good enough, and they aint expencive, no need for anything much better right now unless u wanna future proof

edit : btw, i run +5200 X2 AMD .. with 8800GTX, 2gb top end ram, etc.. and the +5200 doesnt keep anything down.. so if your budget u could probably go a little lower, but id suggest a 5200 or intel equivelent. plz list al the hardware u need for that price btw

and for 500-600, youd only get a pc that run games on low or medium settings.. pcgaming is expencive what can i say 

give us the price u wanna pay, and what u need it for..

and if you got a PCI-E slot in your pc, or just tell us what motherboard u got

ill let u know what is good, what u should get, etc.. dont mind helpin :) 

duke nukem... hopefully
