now for this rig i need a good graphics card to finish the beast off i have a certain budget around 150 i been looking around and the ones thats caught my eye has been the ATI Raedon 5570HD and the Nvidia GTS 450 both of these has had great reviews im really stuck, if you could give me advice on which graphics card is best for the buck please say
Keep in mind i want to be able to play Battlefield Bad Company 2 COD Black ops and Medal Of honour all at maxed out

thankyou.

GTX460/470 or Radeon HD6870/6850 for performance

You might get there with the GTS 450, but not even close with a HD 5570. Start here for how the 5570 stacks up,

Battlefield: Bad Company 2 GPU Performance In-depth > 1680x1050 – High/Medium/Low - TechSpot

and an idea how the 450 does,

okay thanks guys think im gunna go with a GTS 460 thanks alot big help !

I found a 465 fo $150 on sale at Frys one day and it performs amazingly well. Essentially as well as my gtx480 on the games I've played on both of them! Amazing bargan.
