Im about to buy a new laptop and want to get the best value. While looking on lenovo's website I found the y550 series idea pads. They seemed like a pretty good deal since I will be doing some light gaming but I noticed that all the builds came with only 1gb of ddr3 ram. I know a lot people recommend 2gbs for vista. I am unfamiliar with ddr3 and wasnt sure if 1gb would be enough for the computer to run fast.
