Advice on upgrade to gtx560ti and psu

[targaryen26]

hello,
i am looking to upgrade my system as much as possible (you can see my specs below) and would like some advice... please . i am most concerned about the graphic card and psu. I am planning on getting a gtx 560 ti (http://www.newegg.ca/Product/Product.aspx?Item=N82E16814125369) and was wondering:

- what psu will i need for this system and the 560 ti upgrade? what do i need to look for when buying a psu - i have searched and could not find much info on what to look for in a psu

- is the 560ti too much for this system? will i be bottlenecked by the CPU? any other suggestions for cards? i was thinking alternatively maybe an ati 5870, ati 5850 or even a gtx460

thanks in advance

You'd need a quality 400w unit to run a single 560 Ti, a 500w PSU to overclock it all the way, and a 750w unit to run two in SLI fully overclocked. For info on what constitutes a quality unit, refer to:
http://www.tomshardware.com/forum/257075-31-guide-choosing-parts
The PSU section contains plenty of links to tell you all you need to know about choosing the right unit for your needs. I'll make two suggestions that I feel would serve you. As I don't see any reason to get any unit less powerful than this one, here's a 550w pSU to start:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016
This will run a single card just fine, and if you have no desire whatsoever to run SLI/CFX in the future, it will also run more powerful single card setups. This next one is more powerful, on the same level for quality, and actually cheaper after the rebate:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817371049
I'd recommend this one in any event, as it's a steal and could run all but the highest end dual-card setups and easily power a single dual-GPU graphics card.

A 560 Ti running in tandem with that CPU certainly would be bottlenecked in various situations (especially poorly optimized single and dual-threaded games, like the original Crysis and Starcraft 2, and to a lesser extent quad-core optimized apps) but that's no reason not to buy it. I'd go for it and then make upgrading your CPU a priority after that. I have based everything I've said on the assumption that you wanted to optimize gaming performance, so if there are other considerations, please do tell
