Looking to upgrade my computer

That is a good computer. All you need is a good graphics card. And for up to $300 you will have no trouble finding a good one.

You could probably go with an MSI GTX 560 Ti Hawk. They're selling for around $265 (in America) and it is an extremely good card. As you can see in this high-end GPU list, it's ranked 9th and overshadows most other cards.That particular card also comes with a 2 year warranty.

However, if you want a 3 year warranty and slightly better performance you could go with an EVGA GTX 560 Ti. It's selling at just under $300 but it's a solid card that will be able to play most if not all games on high settings.

Interested in getting the MSI card, what recommended PSU should I get?

On Newegg they do not specify the power requirements. But it is safe to assume that a stock PSU will not do. Get a nice Antec 650W and you will be safe. Also make sure it fits into the space. The thing is pretty big.

I suggest CM Silent Pro M600. Silent Pro M600 - Cooler Master - Leading Provider of Computer Case | Cooler | Power Supply
Will be enough for that conf.

If you're wanting to stick two a card under $200, I would go with the SuperClocked version of that card.
Newegg.com - EVGA SuperClocked 01G-P3-1461-KR GeForce GTX 560 (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card

If not, take a look at the two cards I recommended in my previous post.

You should also take a look at the below thread. It has a lot of useful tips for anyone planning to upgrade their GPU.

For a GTX 560, you'll need at least a 500w PSU. I would go for an Antec 650w - 800w to be sure. Alternatively, you should look at the combo packages that sell PSU's and graphics cards together. In particular look at the following deal.
Cooler Master Silent Pro Gold Series 800w w/ MSI GTX 560 Ti Twin Frozr III

Piece of cake. Last time I did it :
