Buying a New PC! NEED HELP! URGENT!

With your budget, A monster gamer is out of the question but you can get an improvement over your current system. The best option (IMO) I found would be using the iBUYPOWER Gamer Power NE711i Desktop PC for $450 here http://www.newegg.com/Product/Product.aspx?Item=N82E168... and since it does not come with a graphics card, putting your GT 430 in it until you can afford more than $100 more for a decent graphics card. You'll have decent enough frame rates in some games (with lower setting) for now as seen here http://www.game-debate.com/gaming-pc/index.php?r_id=137... simply select the game you're interested in playing and then select game analysis and it'll show the expected frame rates
Hope it helps

There is this good one on Ebay here: http://www.ebay.com/itm/AMD-FX-8320-3-5Ghz-High-Speed-E... Its only 24 dollars out of budget

Heres how I can help you. I can narrow down one place not to go from my experience. CyberPower pc is a very bad company to deal with. They took my money but didnt give me what I paid for. I cant tell you how sick that company makes me feel, how much money I feel I wasted on them.. never give that p.o.s. company your money.. dont trust the good reviews.. look at the bad look at what can happen to you.. buying a pc should never be a gamble.. that company should not stop until you got what you paid for.. CyberPower isnt that kind of Company

My best advice would be to go onto TigerDirect and look at the barebones system kits; seem to be very reasonably priced. Comes with most components that you need for under 500 depending on the components. Also, you know exactly what you are getting versus some of those prebuilt crap boxes. You also get the enjoyment of putting it all together  ! I did the same and it cost me 350 after shipping with everything but the GPU and HD. Threw a Radeon 7870 in there and couldnt be happier with it. Especially with the OC'ed card and GPU.
Happy hunting man
