Hi all;

I have a radeon HD 7900 series video card. It's an upgrade to an old system with this mobo + processor:

Motherboard: Gigabyte x84-DS4
Processor: Intel Core Duo e8500

My questions are:
1. Do I need to get a new mobo and processor to get the most out of this card?

2. What do you recommend I purchase to support this card? My price range is $250, but feel free to go over a bit if that's the smart thing to do. I'd hate to lose a bunch of performance trying to save $50.

Currently the machine is used for World of Warcraft and Starcraft II, Skyrim, and a few other games.

Thanks in advance!

You may want to upgrade the CPU. I don't think it'll keep up with a R9 280 well.

So a ECS Z97 Machine and a i3-4330 may do. This would allow you to an i5 or i7 for later.

Some would argue that for that price, there may be a lot better performance. So here:

An 8 core processor for $139.99. That's a jump to the light speed.. . I never owned an AMD machine but my friends have. I always considered them happy creatures. I think I want to be one, too. Thanks.

Not really... a i7-5960X, in theory, would overpower an FX in just about everything even if it also have 8 cores. The 8 cores on the FX is weaker than an i7-4770K. And also, the i3-4330 combo has more upgradeability. But whatever, I guess.
