E248WFP is the perfect choice dude....if you want more fun go for Dell 2408Ultrasharp model its awesome....you can get some very gud deals for this on TE...
A 22 incher will save you money in the graphics dept. Though I'm going for a 24" myself, I would be able to play at far higher settings on my new yet to be purchased card if I'd stick with my 22". Only reason I'm getting the 24" is cos I'm getting it a really good price!
