Which is A Better Computer?

If you are looking for the cheaper option here, go with Acer... it will be fine with light gaming. Plus, the wonders of computers allows you to upgrade it in the future, but if you are doing heavier games like COD and GTA IV or whatever go with the Dell... May I suggest another? The Dell Inspiron 15 is a great buy, a good price tag and good amount of memory (4GB) and a Intel Core2Duo (2.2GHz Dual-Core) processor, I like it. ( I have an Inspiron 1545 personally and I love it!)
