Graphics Card Recommendation For Pentium Dual Core

The card will be insanely bottlenecked, by the pentium. Look into upgrading your cpu to an i5-2500k which is a great cpu and then the card won't be bottlenecked at all. But what is your budget?

What do you mean by "Insanely", ordered a EVGA 550 Ti and i'll change
Power Supply, Topic Closed.

Insanely as in the fps will be very very low. The pentium will bottleneck the 550ti unfortunetly, well good luck. I still advise upgrading your cpu, in case you want your son to be able to play above 20fps

Yes, it will have some bottleneck. But still don't know if this will be a problem.
U will have a great performance for now.

Opinions:

1- Later u can upgrade ur cpu and 'unlock' more of the VGA power, and, with the new cpu it will get u a massive epic win!
2- Usually old Pcs get old HDs, that is considerably slower than today.
Even if old HDs is 7200rpm, today 7200rpm are faster, cause of the higher data density. If don't have money for a SSD (could be overkill), buy a 1 TB 7200rpm HD, it should help a lot in common tasks.

Well Thanks, for now i'll just get a EVGA GTX 550 Ti and a new Power Supply
within a couple of months i'll upgrade to one one of those new Boom Boom systems. The Hard Drive BTW is a WD Blue something 500 GB.
