As I've posted before I'm considering an upgrade path for my current machine and have run into an issue earlier than I hoped. Basically my 7900gt is failing for the 3rd time since I got it. I'm going to be sending it in for warranty replacement, however I really don't feel the burning urge to sit around waiting on the card to be replaced using a lower end card in the meantime...

I'm considering:

It's only a 512mb card instead of the 1gb Asus, however from what I'm seeing most benchmarks don't show a notable increase in the 1gb card... I've also been unable to find any benchmarks that are geared towards multiboxing .... something about us being abnormal i'd guess.
Anyone have feedback on the amount of video ram? Would it be worth the extra $50 for a 1gb card?

Thanks,
