Hey, i just sold my old 4870 for 135$ and I need to buy a replacement for it. I dont have much time because I've gotta leave the US for the summer and I'm gonna be taking my computer with me. I was looking at the 5850 but i noticed that the 5770 is cheaper. So guys help me figure out the cost/performance trade-offs and the resale value over time. Thanks I'd really appriciate any input.
