Which GPU and powersupply?

[Alazzer]

My system is a
Corsair 60 case
Asus Maximus Hero 7 Motherboard
i5 4670k 3.4 Processor
Cooler Master 650 non module (current power supply)
1333 samsung x 4 @ 2gb (current ram)
Seagate Barricude 2tb
XFX HD 5770 ATI card (current card)

I wanted to know What Graphics card I should get or Cards I was thinking of a 280x But would like to hear which brand or other alternatives for close to the same price, aswell as What Power supply I should get(Just want to be able to crossfire with some room to Overclock).

Ram is to a far lesser extent, just any insights into what I should get.

I agree with you for the R9 280X. MSI, ASUS, XFX are great cards, it depends on your taste .

Get a 750W so that you can crossfire in the future.

Ow I forgot to mention the Sapphire. (I own one).

Great choice I was about to recommend the R9 280X too. If you are looking for that then get a Sapphire brand for cooling and performance.

If you Crossfire a R9 280X and also overclock in the future then get at least 650W from Tier 1-2. Here's the list to assist you out.
