dude, please, get a good corsair or antec power supply, if you dont, you will suffer the consequences.

Yeah that's what I heard, but I don't know which to get cuz a lot of reviews say they have DOA problems :s

I wasn't asking how much wattage I need, just needed a direction on which one to buy

You wont need a PSU above 600w btw. Dont go overboard and get anything above 700w.
You could get away with 500-550w if you dont overclock.

8gb 1600mhz ram vengeance and case i dont recommend haf 922 but HAF XM is pretty good, but i recommend fractal define r4 its quiet, sleek and good quality and for psu u shud get a modular one from corsair anything 550-650 should be fine

Silverstone also makes really nice PSUs. They are right up there with corsair and antec

Recommend the 650HX from Corsair. You don't really need 650w, but it's always better to go overboard. If you're feeling saucy, and potentially plan on running SLI cards in the future, get a 750w (either corsair HX or thermaltake toughpower) and be a boss.

Thanks for the help guys, I've decided on my PSU and RAM. The only thing I still need help in deciding is the PC Case.

Could you explain why you recommend one over the other?

EDIT: nvm, I just took another look at the case you mentioned and I actually quite like it

you don't really need to spend a whole lot on a pc case unless you want to, at the end of the day it's just a bunch of plastic and metal that holds your shit

I'd say a good psu might be like 125-140 bucks, 4 sticks of 4 gb 1600mhz ram(if you're running 64 bit, for 32bit 6 gigs should be enough) should run you like 60-70 bucks, then for a good mid tower case, 50-70 bucks should be more than enough

Getting the ssd will be an amazing boost.
Also you should get no less than 8gb of ram.

antec 302 is a nice, cheap case. As for psu if you're going for single card configuration, a good 550 watt is really all you need as your components are very efficient: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151119&Tpk=seasonic%20550. I have a 670 GTX with an i5 3570k@4.0 ghz with a gold-rated capstone 450 watt psu and it runs without any hiccups. Ram you could just get any 1600mhz ram (mushkin, g-skill are good and reliable ones).

i7 seems like overkill. You can save $100 with an i5 3570k and you wont' notice the difference. You can also easily overclock that to 4.0 GHz without changing voltage at all (would work on i7 too, but again, it's $100 more for performance you don't need).

Anything more than 8 GB of RAM is overkill too, but RAM is dirt cheap.

I recently built my PC around Christmas if you have not bought the components i would recommend getting the i5 instead you will save yourself 100 bucks and you can use that to get a better Motherboard that will improve performance i Bought the MSI Mpower motherboard it is great Eufi Bios and Overclock CPU to 4.5 with a single Buton ill link you http://www.newegg.com/Product/Product.aspx?Item=N82E16813130660
The board is great and will last a very long time watch the Video. As for the case if you can afford it get the Cooler Master HAF X its really nice or the HAF 932 good cases i bought them.

I know you're trying to be helpful, and this is likely going to sound rude, but periods have an amazing propensity for eliciting coherent ideas.

Throw a period at the end of your sentences and move those random capitals to the beginning of the sentences and you're golden.

:p

I hear OCZ has some pretty quality, reliable PSUs available

periods don't elicit ideas you might want to hit the thesaurus again champ

I would just get a modular gold-rated psu as they are not much more expensive than a modular bronze-rated psu. That being said I would buy from any of the following brands: Seasonic, XFX, Rosewill Capstone, Corsair. If you just want to go with a bronze-rated psu, Antec or PC Power and Cooling are good alternatives.

Still trying to sell a new Corsair TX650W if you are interested.

Just get the case that looks the coolest.
Almost all ATX cases you find will support your configuration + the case you choose probably won't add any extra "performance".
If I were you I'd buy a better CPU cooler. The one you chose is great for the price, but performance wise, it'd be better to spend more on a better cpu cooler, and less on the case.

pretty decent variety of color options, excellent case.

Fractal Arc Midi, Lian Li PC-9F, Haf 922, 500r, cm storm, antec 302 are all pretty good atx cases.
