My current pc spec: Motherboard: ASUS Crosshair IV Formula RAM: 8GB (2x4gb) 1866mhz VENGEANCE GPU: ASUS EAH5870 HDD (2x): WD Caviar Blue 500GB sata3 6Gb/s PSU: LC Power Silent 550W 140mm 6550GP2 CPU: AMD amd phenom ii x6 1075t
So here's my question: I'm thinking of buying a new gpu (the radeon hd 7990 when it launches), but I'm not sure if my CPU is up for the job? I hope you can help me here on tom's hardware .
You will definitely see an improvement by upgrading your CPU. Most games aren't that CPU intensive, so you'll only see a small improvement in fps. However if you are doing something like streaming yourself playing games, then it might start to feel chunky.
What I'm worried about is if 550W psu will be enough. Not sure how well the power consumption of the 7990 is going to be, but it's always good to stay under 80% psu load, so 550W might be pushing it a bit. It may be good to upgrade to a 750W psu. I'm no expert in PSUs, so someone else should confirm with me.
550W will definitely NOT cut it for any Dual-GPU solution. What exactly are you trying to play/do? Also, what is your resolution?
