I am very bad at this stuff. I'm going to upgrade my PC soon. Current specs: i3 3220 and 2GB RAM.
I'm planning on getting the 7770 and increasing my RAM to 4gb or maybe 8gb if i have more money left. and also upgrading to Windows 64-bit so that I can use more than 3.5gb xD

I can't buy anything in my country so I'll be using ebay. Actually, I can buy them here but too expensive. The 7770 is over $250 here :/ 

I've heard that Corsair is the best brand when it comes to this stuff.
Will this work? http://www.ebay.com/itm/CORSAIR-Builder-Series-CX500-50...

I also have a feeling that I might need to change the motherboard... I don't know the name of this motherboard. It's Acer. It has a PCI-e 16x(i think thats the name haha) thing for the graphics card. I'm not using that computer right now so I can't check.

My budget for the power supply is around $100

Okay. but in the amd website, it says "500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended7" I have no idea what 75W 6-pin PCI Express power connector is(LoL), but is that in this power supply?
