Hi All, This is my first post and I've got a question about the Zotac 680 4GB. I'm not familiar with that brand, and I've currently got an EVGA 680 SC+ unopened. I've held off opening it till I was positive it was the best card. I ordered it on impulse and now I'm having second thoughts. I had also ordered a XFX 7970 BE DD but I returned it already. I'm concerned about only 2GB vram on the EVGA 680 SC+, am I over thinking this? Is Zotac a good name in quality. I've googled it, but come up with suprisingly little data on them. Is a stock 680 with 4gb vram gonna be that different than the EVGA 680 SC+? It's the only 4gb 680 I've found that's actually available. Although, the EVGA Classifieds are coming out soon, but the odds of me actually seeing one is slim to none. Thanks for any input! PS - I'm upgrading because my XFX 5970 BE is on the fritz and XFX is dragging their heels with the RMA. Or wait and see how AMD 's Tahiti 2 pans out? However, after constant problems with drivers for the 5970 I'm ready to give Nvidia a try.
