Yeah, as for my pc. I got all the parts as a christmas gift, and I also put it together myself. cost 325, but its an amd quad core 2.8ghz, 4gb ram, and a 1.5tb drive, but I still havent gotten around to getting a graphics card. It has the internal raedon 4200, but it just doesnt do it for most games.
As for a laptop, I just bought an acer aspire 5515 for 140, plan on upgrading the cpu to a dual core, and it should be a good little travel laptop.
Also like ps3 said, I like the amd processors because they are less expensive. You have to be careful when overclocking though. I saw a video where they put amd and intel chips next to eachother, overclocked them to the full potential, when the intel got too hot, it just shut off, but the amd kept going until it pretty much blew up/caught on fire. this was years ago though.
