I'm looking to replace my old computer, but will probably buy from the store to keep costs down. I'm looking at 6 computers. One has an e2180, another an x2 5400. The third has an e2220 and the fourth an x3 8450. The first two and the last two cost the same and have the same amount of ram and hard drive space. My last option is a pair of notebooks, one with turion 64 tl-60 and the other with a turion x2 rm-70. Which of those two would be faster?
