I have a Radeon HD 6750 1GB and get around 30 fps constant on max settings with that and my AMD Athlon II x4 645. Theoretical performance comparison. They don't have a 2GB model listed though. According to this the cards are also fairly similar is some specs, but both outperform each other in their own ways.
i have a friend who has that card in combo with one of the most popular cpu to overclock (the intel core 2 quad something), and he runs it just fine, so yes, it will run it just fine
uh, no, your card isnt even CLOSE, to similar, your's is one of the WORST ever made in fact (the intel hd 4000 is better then your gt 610)
