I'm currently running a Core2duo 2.2 Ghz with 3 gigs system ram, a Sapphire Radeon 3870 512 Mb on Vista Home Premium 32 bit. I'm looking at either a new Core2duo 3.0 Ghz or a new radeon 4870 w/ 1 Gig. Thoughts? I wonder if I'm really pushing the 3870 with my current processor. Power is not an issue , as I have a nice Antec cranking out plenty of power. Thoughts/experiences/suggestions?
