Currently, I have a Radeon 5770 running at stock speed. My wish is to run BF3 and COD MW3 at highest settings in 1920x1080 resolution. I have no thoughts to overclock it. Hence to achieve smooth performance, I am planning to purchase another 5770 to run both the cards in crossfire configuration. Currently I find used 5770s online for £60 (~$90).
Do you think there is a better alternative to buying another 5770? You can throw in any suggestion that is appropriate. For e.g., selling the current card and going for a completely new model (in such lines). Please note that I don't fancy anything that gives me more than 50fps. For me, it doesn't matter. In other words, I don't want anything monstrous. I can put in max $300.
I currently have a AMD 720BE running at 3.6GHz (overclocked). I have no plans to upgrade it. Also I have a 550W PSU. If needed, I can buy a more powerful one. My motherboard supports 1 x 16x or 2 x 8x. Hope it won't matter.
Thanks in advance, guys!
