New computer help (graphics card)

[Meowingtons]

I bought a Zoostorm Pentium DC E5800 3.2GHz, 4GB RAM, 1TB HDD, DVDRW
Motherboard - ASUS P5G41T-M LX2/GB/SI
300W PSU
8 x USB,
1 x PCIEx16,
1 x PCIEx1,
2 x PCI,
5.1 Channel Audio
DDR3 1333
2 x 2GB DDR3 1333 Sticks in the unit

What I want to do is install a graphics card (dont know much about computers) and I need a better power supply, what would be the best? (for battlefield 3) I was looking at the GeForce GTX 560 Ti'Maximum Graphics Edition' + would this work with my pc and could you suggest a power supply?
Thanks in advance

That 300W PSU will definitely die with a 560ti (or anything for that matter . Good thing you ask.

1 x Corsair Enthusiast Series TX 650W V2 High Performance '80 Plus Bronze' Power Supply (CMPSU-650TXV2UK) £70.99

Depends if you are skint or can spend a little. A Corsair TX650V2 / TP-650 will power up to a GTX580. The Antec TP-550 / XFX Core 550W good up to a 570. The rest probably up to a 560ti, maybe 570. Recommendation would be middle of the road, a TP-550.

BTW compatibility and upgradability is a weird thing with pre-built. I wouldn't have second thoughts about an OcUK machine as they use standard components, but no idea about a 'ZooStorm'.

Can you get a picture of the inside? I'm having second thoughts about you being able to fit a 560ti in there (and the PSU of course).

I cant find a picture with the case open + I am waiting for the pc to arrive still. I did some researching and its apparently a std ATX unit case
