GPU:
could be one of those. it is a great price performance, i'm sure it will handle diablo 3 flawlessly at 1080p:

but if you want better card with what money you can go with a:

it has better performance than the first one, but i think that the first one will already run very well diablo 3...

XFX Core Edition PRO750W (P1-750S-NLB9) 750W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Power Supply
$114.99 and a $25 rebate makes it 89.99

EVGA SuperClocked 015-P3-1582-AR GeForce GTX 580 (Fermi) 1536MB 384-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
$424.99 and a $20 rebate makes it $404.99

This combo will play any game at any settings and resolution and get very good fps. It doesn't get much better than a GTX 580 unless you increase your budget. Evga also gives a lifetime limited warranty on the card should you decide to keep it for more than a few years.

That would do a pretty good job.

Diablo 3 80 fps + easy!

yes good gpu but that is too much money for a psu unless he is going for 570 SLI there is no need of jumping to gs800.. a good branded 600w psu is enough for every single card out there.
so keep some money from the PSU in invest in a good GPU, the 580 are now in a good price, because nvidia stopped the production of 580 and 590 so maybe waiting some more time the prices will drop even more for those guys it is indeed a good option if you want nvidia.

7870 (similar performance to GTX 580 while drawing way less power and it costs ~350$) + any 650W+ unit from Corsair, Antec, Seasonic or Pc Power and Cooling. Should easily stay under 500$  

So i really dont need to go with a psu more than 600w?, the thing i hate is newegg dosent list what that gpus draw for power ,,,unless im looking right at it an not seeing it (its happened before lol)

Well typically a 6 pin PCIe connector draws 75w and an 8 pin can draw around 150w. So you're looking anywhere between 150-300w for a high end card. Then it can fluctuate +/- 20% load and idle. A 600w PSU will be more than enough for one high end card. I would not suggest the Corsair Gamer (GS) series, had one die on me in less than a month. The other Corsair models are better built and I would recommend..

well i did not have any problems with it so far, but i agree that the GS series are too expensive it worths much more going with other series, but if you got a good price on it i don't think you will run into trouble, i am running 2x 560 ti in SLI with a GS700 i have it for only a half year, and no problems so far.

but i don't recommend them only because of the price.

Ok you guys gave good suggestions, Ricardo i really like yours. Inzone has the right idea to. honestly i don't see as much wrong with a GS corsair as i do with "PC Power And cooling" this guy needs atleast a 600-650 watt to be safe. Honestly if i had to say what is the best bang for buck best option to get right now.... I would have to say either the 448 Core GTX 560 ti, or the GTX 570. now most people may say a GTX 480 is better and has more vram. Well it all depends on your airflow and power supply. the GTX 480 is the Monster Card from fermi that we all know. the GTX 570 is what replaced its performance level. Now if your gonna run Diablo 3 on Highest settings trying to get 60 fps stable.... your gonna be two things, VRAM and horse power. the difference between a GTX 570 and a 448 core is so small its more worth getting a 570 now tho since prices are dropping. Both cards have the same amount of vram so either one of those cards will do.

The Radeon 7870, the Radeon 7950 are both good cards as well. But you must be careful with the brand you get. Some radeon cards can be unreliable but for the most part AMD's Graphics arent bad enough for me to talk down about them. With two gigs of Ram with the 7870, performs similar to a 580... but its 100$ more than the 570... Between the two, i would pick the 78070. Because like i said you need VRAM, the more going on in the game and more visuals and graphics enabled just eats VRAM, So 2GB will be worth it. The 7950 is a good step up if you can get it and a good power supply. ANd with AMD price cuts coming... it makes a damn good card at point.

Now what we havn't discussed is Kepler. NVIDIA is rolling several different out different GPU's are different price points in a little less than a month from now. Right now there really isn't much we can share on performance and pricing yet but we can keep you posted if your interested. The only Kepler card on the Market right now is so popular though that it stays out of stock... or is jacked up in price on ebay or other websites...

Power Supplies:
With any of the cards listed, a Good Name brand quality power supply, A 600-750 watt will be plenty and more for any card we have mentioned. If you plan to do SLI/Crossfire and add another Graphics card later on to ( Bragg off to your girlfriend ) and get more performance a good 750-850 watt power supply should be more than capable for anything two way.

once again thanks for the input people , ive done some looking and i think i found what i wanna try, gimmie your thoughts/concerns

gpu:http://www.newegg.ca/Product/Product.aspx?Item=N82E16814102981

and the psu:http://www.newegg.ca/Product/Product.aspx?Item=N82E16817207015

tell me what you think

it is a good option but personally i would take a little cheaper psu since 750w is really too much for a single card, and invest on a 7950.
http://www.newegg.ca/Product/Product.aspx?Item=N82E1681...

and the psu would be something like this like i have recommended later:
http://www.newegg.ca/Product/Product.aspx?Item=N82E1681...

it will be already enough for that video card and you will stay on your budget with a higher graphical power.

but if you really need a 750w psu your option is also good enough.
