How good is this?

[bladecnh]

OK so I prepared my new configuration and part of it is ATI HD 6850 GPU so I need some thoughts about it, how good is it? Will it be able to run games in at least next 2 years? How many Watts PSU should I get for it.

As about PSU here are my specs:

MSI P67-C43(B3) 1155 Intel P67
Intel Core i5 2500 1155 3.30 GHz
G.SKILL 4GB(2x2GB) DDR3 @1600
HDD 500GB WD5000AAKS, SATA2, 7200RPM, 16MB Cache
DWD-RW LG, SATA, DL, 18x
ATI HD 6850 DDR5 1 GB

I was thinking of getting a 550W PSU, but I'm not sure.

Thanks in advance.

amd suggests a 500w psu:

My short list of quality brands would include Seasonic, Corsair, PC P&C, XFX and Antec. There are others.
Do not go cheap on psu quality!

Do not worry about how long a graphics card will serve you unless you know the requirements of games you will play in two years.
If, or when the 6850 seems inadequate, sell it and buy the next best thing.

For planning, a 650w psu will run a singleGTX580 today. 700w for a GTX590. I expect future cards to be more efficient.
One of the better priced units today is the XFX 650 for $70 after rebate. Modular too.
