My specs : GTX 550 ti, AMD Phenom II X4 965 processor 3.40 ghz, OCZ StealthXstream II OCZ600SXS2 600W powersupply, I have about 9 inches of length in my pc case. I believe that my motherboard is this one http://www.msi.com/product/mb/870S-G46.html I need to upgrade my computer's gpu so I can run bf3 high with 60+ fps, I was thinking of getting an gtx660 ti but it's too expensive for my age (16) and I thinked about sli the gtx 550 ti, but I don't think my power supply can handle it. anyone could help me out? with a budget of 150 dollars. thanks.

A typical 550ti will require 152W at max load. That is about 12.7A on the +12V rail for each card. With your PSU's 3 18A +12V rails, you should be OK with 2 550ti's. 2 550ti's in SLI will be an adequate combination for BF3 depending on your display's resolution. I doubt you'll maintain 60fps with BF3, tho. Here is a video of a similar setup playing BF3 at 1920x1080: http://www.youtube.com/watch?v=CbXTctPyv9A

But keep in mind that low and mid range cards suffer from micro-stutter in some games when using SLI or Xfire.

While maintaining 60fps is always nice, as long as you can stay above 30fps, you should have decent gameplay. 30fps is about what the human eye detects as fluid motion.

My bad. You are correct. That board doesn't support SLI, just Xfire. I should have investigated it a little better. Most dual card boards today support both. I assumed wrong with yours.

In that case, you are near the max in cards of the $150 range. If you can squeeze out a few more dollars, go for this HD 6870. I have used it in several builds and it performs excellent at gaming up to 1920x1080 resolution. If you game at lower resolution, like maybe 1680x1050 or 1440x900, you may even get 60 fps in BF3. But even at 1920x1080 it will perform nicely in BF3.
