I do run at 1920x1080 and my 4850 does an admirable job for the most part. I usually pick up older games on-sale on steam, but as I've said I'm noticing the need to turn more settings down on 'newer' games as they go on sale. That and as a WoW player I experienced the 15-20 FPS drop that seems to occur every-time they release an expansion
I did go ahead and purchase the 7770, seemed like a good buy at $110, assuming rebate. I did see some being sold at micro center for $90, but after looking up that particular model seems like gigabyte released a batch with a higher failure rate. Anyways it's good to know I should see a decent performance boost, plus I'll get access to DX-11 and all the eye-candy that entails. I'll post my impressions once I receive and install the card.
Thanks for your input.
