Compatibility of nVidia gtx560

[xxf4rhanxx]

Hello,I'm new to the forums at Tom's Hardware, and I'm pretty ignorant when it comes to computers, so I apologize in advance if I sound like an idiot.

So this is the thing, I've got a computer with:
CPU: intel i3-530
RAM: 4gb corsair xms3
GPU: Intel hd graphics
PSU: 450w
Motherboard: Asus P7H55-M

I want to buy the nVidia gtx560 GPU, and I've had a good hard look at everything and it seems to be compatible with my motherboard. I'm really stressing if I have a big enough power supply, because when I research it I get many different answers. I was wondering if I have enough power to support the gtx 560? If not, what's the best GPU I can get with that sort of motherboard and PSU? And I might also get the i5-760 (it's the previous generation, I know, but 2nd generation intel CPU's aren't compatible with my motherboard). If I do, would that be compatible with everything that I've got?

I would really appreciate any help at all, I'm really confused at the moment. I know I've got a few questions, but the one I really want to know is if my computer will be able to support the gtx560. Thanks!

What make is the PSU? But even if your PSU is a decent brand I would still recommend buying a new PSU of at least 600W to be safe. I would also recommend going for the GTX560Ti. The price difference is not that much for the performance boost you get. Other option is the HD 6950. Both of these cards perform the same.

So if I want to buy the ti, is 600w enough? and also ti is pretty much out of my price range. I was thinking about getting a good gpu (ti, as you said)) and psu for at max. AUD$320.

and this power supply

or get a Corsair TX 650w other wise just get a 500W Antec Gamer should be enough my GTX 580 runs on a TX 650w with no problems and thats a power hungry card compared to 560

i have 2600k oc @4.5. 16gb ddr-1600 1.5v ram (no oc). 2 ssd and 4x 1tb hdd in raid.
2 optical and 2 gtx 560 ti in sli. 2 dell 24" lcd on load on a ups and the max load i got was around 550.

if you don't oc, 450 should be fine, but if you do oc, get 600 to be safe.
