Summary: $235 XFX 6950 to replace a gts250 in a x4 630 with 550 watt psu. Good for it or leave it?
APPROXIMATE PURCHASE DATE: this week
BUDGET RANGE: USD $250
CURRENT GPU AND POWER SUPPLY: Antec BP550 Plus 550W Continuous Power ATX12V V2.2 80 PLUS Certified Modular Active PFC Power Supply
Current GFX: Msi 250gts 512mb
OTHER RELEVANT SYSTEM SPECS:
Athlon II x4 630
Is the PSU sufficient? It is only running 1 local hard drive and the athlon x4(95 watts), So I would hope that 550 watts is enough. I have no idea what to look for in my PSU specs or how to check the volts per rail to make sure it will work.
Card I'm thinking of buying:
XFX HD 6950 800M 1 GB DDR5 PCI-E Video Card HD695XZNFC
Price $235 with free shipping after mail in rebate link
i suggest that you don't furmark test your card. I have my 6950 unlocked and overclocked as well as my cpu and I reach ~500W when stress testing my gpu. When I'm gaming I never go above 400W so 550 should be just enough especially since you you specified that it is 80+ certified.
