Went to CompUSA to check out new cards. Visiontek GE4 Ti4600 is $400 and the PNY GE4 Ti4600 is $300...they seem pretty comparable side to side. I haven't been able to see any reviews on PNY's card but have read great things on Visiontek's. Anybody seen anything on PNY's card and is it work the $100 savings for the same Nvidia chipset?
