i have a pentium(R) Dual-Core cpu E5400 @ 2.70GHZ, e692 MHZ, 2 core(s)..any one tell Which Graphics card would suit my PC.

what psu do you have? wattage and brand, well if im in your situation i would definitely go for an ati hd 5770 msi twin frozr if you can still get one of these. or the gtx 460 evga or an msi twin frozr version. both card are cheap now a days if you can find one on ebay or from a 2nd hand store. they are both dx 11 and will give you the option on saving money so you can upgrade to a q6600 quad core
 
ehh i wouldent get the 460 (5 years old, overheats,slow,uses obscure amounts of electricity, and geforce gt 730 out preforms it and is much cheaper)

@BlueBossGamer with all due respect gt 730 would never be at par with gtx 460. dont be confused wiht the numbers bro 730 might be a higher number than 460 but that doesnt mean its faster
 

really WOW i did not know that hopfully you can understand sarcasm but lemme tell you about my previous gpus i started with a 460,480,580,670,730(for htpc),770,970 belive it or not i recycled my original processor and used it for my htpc it destroys my 460 hell i still have in my gpu tub and with all do respect just because it has a 60 at the end of it does not mean it can run all games and 60fps take it from someone who has owned both
 


 
You probably wont have to upgrade your power supply because there are many graphics cards out there that use so little power that it would be unnecessary. I need to know what model motherboard you have. If it is a pre built machine, I need to know the model.
