Radeon 4870 x2 versus dual Radeon 5770 in crossfire

[Valectron]

Hello everyone, I have a question in regards to a Radeon 4870 x2 versus dual Radeon 5770s in crossfire. My current motherboard doesn't support crossfire but I do have two 5770s. My question is however, I plan on either buying a new motherboard to crossfire these or get a Radeon 4870 x2 as posted here http://www.ascendtech.us/itemdesc.asp?ic=VC2GATIHD4870X2.
I need to upgrade from my processor eventually one day, I have a i5-750, so I was wondering which would be a better investment. Either go with the motherboard that leaves me with the LGA 1156 socket and crossfired 5770s, or keep my motherboard for now and only spend my money on the 4870 x2 if I want to upgrade my processor in the future. Any help would be appreciated.

It's a close call. I think the DX10 performance of the 4870 x2 is a bit better than 5770 xFire, but the 5770s will give you DX11 support and a few other improvements.

The best answer would actually go for a single card solution instead. That will allow you to upgrade your CPU later on and still carry over your GPU. The HD 6950 is a great card and will out-perform both. The GTX 560ti has some good OC versions that will be about the same as a stock 6950.

Your CPU will due you fine for a good while and the LGA 1156 is a dead socket so there's no upgrading your CPU alone. Mobo + CPU upgrade at the minimum.
