Get another 4870 512 and crossfire for about $175
Sell current 4870 and buy 4850x2 for about $150 ( price after selling old card)

WHich do you guys think

4870x2 definitely..

Go for the 4870 Crossfire. No reason not to, if you already have one 4870. The 4850 X2 is a great card, but it isn't as good as two 4870s.

Rydawg5143,

Two important points that you need to consider are resolution and motherboard

A. resolution, I was in the same boat as you, with a 512mb 4870, but moved up to 2560x1600, and the 512mb is too little for that resolution, so I move the 4870 512mb to another system and bought a 4870x2
-the 4850x2 is as good as the 4870x2 with the benchmarks I seem, but had a major flaw with only driver support by sapphire, no ATI support, but I believe that change with 9.1 catalyst, so it looks like a good choice now

B. motherboard, if you have p45 and up, and you don't game at too high of resolution, than another 4870 512mb would be a great choice

good luck
