My specs: MSI MB H55M-E23
Intel Core I3 550 3.2GHz
550W PSU
8 GB DDR3 1333MHz
and the GeForce GTX 550 Ti

My brother has a really bad gfx card and I want to upgrade mine so I can give him the 550. So I'm looking for the biggest boost I can get for R2500(270$). I have looked at the Radeon HD 7870 LE, would there be any compatibility issues or bottlenecking?
Thanks
