Hello guys.I'm wondering should i buy myself a new video card.I really want it and have the money ,but don't know if my PSU will allow my this update:
My specs right now are:
CPU : Intel i5-3570k @ Stock Speeds
RAM: G.SKILL Ripjaws X 2x4GB @ 1600MHz
GPU: Sapphire HD 6850 1GB GDDR5 Vapor-X Edition
PSU: Cooler Master 460W Elite
I have no problems with my current rig ,even when i boost the clocks of the GPU to very high level --> from 800/1100 to 950/1200 which gives me significant boost in games ,but the performance is still not enought to play the game i want to ---> Battlefield 3 on ultra settings with decent frame rate.So the card i'm looking to update to is the MSI GTX 560 Ti HAWK ,from newegg .Right now i can get it for only 225$ after rebate. --> http://www.newegg.com/Product/Product.aspx?Item=N82E16814127578
I have one HDD,500GB Hitachi,only one fan in the case and one CD/DVD Drive.Thanks in advance!

What about the HD 6950? Is it going to be OK with my power supply because i only have the possibility to buy GPU,new PSU is not an option unfortunatelly.My HD 6850 will go to my parents PC,so selling it ain't an option either.

So HD 7850 have the same perforamance as HD 6950 but will be perfectly OK with my PSU? If that's right,which brand would you propose me for the HD 7850 - it's around 250$ pure price,not after rebate.And btw,my sister will order the things in the city she is right now,in USA.So the check won't be to Bulgaria,it will be to New York.One last question - how is the HD 7850 performance compared to the GTX 570?
