My current setup:
AMD Phenom II 965 BE
ASUS M4A785TD-M EVO
HIS Radeon HD 5770
G.SKILL Sniper 8GB 1333
OCZ ModXStream Pro 600W
Resolution = 1440 x 900
I'm currently browsing around for an upgrade to my HD 5770. I believe my other components will still be up to par. I want a noticeable upgrade, though not something that's going to break the bank so to speak. Currently my 5770 is overclocked @ 920/1300 and my CPU @ 3.9GHz.
I was looking at this as a viable option:
Newegg.com - ASUS DirectCU II HD7790-DC2OC-2GD5 Radeon HD 7790 2GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card
They have another in a 1GB version as well. The benchmarks on the 7790 are twice that of the 5770, and the cost is right within my range.
I will probably try to overclock whatever GPU I decide to go with at some point or another. Any suggestions?
