Maybe.... I'd doubt it though. Because if you want a gaming computer you'd rather buy a better video card before maxing out on your ram. You probably would rather build your own computer instead of buying one. It may sound hard if ur a noob but it really isn't that hard. You need a good solid dual core processor (Intel Core 2 Duo E4000 Series is a good cheap budget processor), maybe even go quad core if you have the money. 2-4 GB's of RAM would be enough. A good graphics card (eg. Nvidia GeForce 8000 series). The GeForce 8000 series are a set of really good cards, so budget some not, ranging from $50-$250 in price. I mean seriously, if you only have $300, you can't get a good gaming computer. As everyone always say "You get what you pay for, nothing more, nothing less.

Yes, check your local pawn shop or look for one that "fell off the truck".

For a gaming system, look at the video card over maxing out your memory. You should be able to get a decent gaming system in the $600 and up range for new, maybe $450 or so for a refurbished system.
