Hi Everyone,

My current rig is as follows:

CPU: i7 920 2.67 ghz
RAM: 16 GB
GPU: HD5870
PSU: 875w

I want to upgrade to a HD7970 Ghz Edition. Will my CPU be able to take full advantage of it? Thanks for the help and advice.

i think there will be no problem because you have enough power supply , ram is 16 gb , and an i7..
Definitely no problem but make sure you have PCie 3.0 slot ..
7970 requires 750 watt minimum you have 875w
Good Luck.......

above is not exactly true.
the card will work and it's a big upgrade... but some games are CPU limited, some are GPU limited.

Your CPU would be the biggest botleneck you have now. I wouldn't put in that video card unless you're willing to overclock your CPU.
I believe the 920's with a good cooling unit can run 3.6ghz to 4ghz.

also, the 7950 is better 'bang for your buck' at around $200 these days.

I wouldn't shell out $300 for a 7970 with the next gen AMD cards out next month.

the card would fit well in your rig ........i also agree with lowriderflow that you should overclock your Cpu......

Overclock for sure. Also with a 920 you will not have PCI 3.0 but it is not needed so don't worry about that at all. This will be a huge upgrade it will be nice.

Do you think the price of the 7970 will drop in a couple weeks as the new Hawaii based cards are released?

Possibly but not by much the 670/680 did not drop much when 700 series came out. Maybe 50 bucks max...

I'm a little confused about the PCI 3.0 requirement. My current card (an HD 5870) sits in a PCI slot. I have noticed that all the 7970 ghz edition cards say PCI 3.0. Will the new card fit and work in my system?

PCI express 2.0 x16 is pretty much equivalent to PCI Express 3.0 x8.
The performance is not cut in half tho, it's reduced by a couple of frames per second and in some cases even less.
Get the HD7950 instead, it's much cheaper and just a tiny bit slower than the HD7970.

Thanks. What is the difference between the 7950 and 7970? Basically, I would like to run Rome2 on Ultra or as close to it as I can get. (I've given up on running it on Extreme for now) and would like to be able to get some decent frames and settings from future games (like BF4 and DA3). I'll probably do a complete upgrade (mobo, CPU, etc...) in a couple years but would like to be able to get the most out of my system in the mean time. Do you think the 7950 is a better fit? I'm open to other suggestions if anyone thinks it would be better.

The HD7970 is about 10-15% better and it's 100$ more. It's not worth it because you can OC the HD7950 to be just as fast as the HD7970.
