I got a sapphire 4870 1gb card coming in tomorrow. The price fell to $299 so though the 4870 512mb card is about $50 cheaper AR...the 1GB of ram seems appealing...whether it will really be effective or not. I know in future games it will help a bit. I already know the performance of a the 4870 512mb card is excellent even at 1920x1200...so I expect to see about the same results. My gaming rig has the 4870x2 in it and the 4870 1GB card is going to be placed in my htpc rig that's going to go in the living room. I'm thinking about pulling the 4870x2 for a while and benching the 4870 1gb card in my gaming rig using fraps in a few games. I got Grid, COD4, Bioshock, and Crysis. Let me know if you want to see some numbers. Maybe I'll just do a little video review on youtube. Not too sure how to post videos on youtube though.
