Building around a 6950/6970

post #1 of 10
Thread Starter 
Hey fellars, I've finally got the cash to do some upgrading. I'm currently operating with my sig rig but have since returned the Q6600 CPU back to its stock 2.4. I'm definitely going to buy either a 6950 or 6970 and I've been doing some research that says that my current CPU will bottleneck either card. I also watercool both the CPU and GPU and intend on doing the same on my next rig.

What processor would you recommend for a 6950 or 6970? I'm obviously looking at the i7 line of products but should I look at picking up a cheaper 950 or something and overclocking it to a desired speed or what? Or, what's the desired speed to maximize the use of either card? 3 GHz? 4?

I also have a 650W power supply. Will that be enough to run what I'm intending here? Thanks.

AMD recommends a 550W to power a system with a 6970 in it, so almost any 650W will be more than enough.

However, which brand and model is it?

Oh good. Even if it's the TX650, it's still more than enough and would even be able to handle the system with two 6970s in it.

Save your money and get a 6950. There's very little performance difference between the 6950 and 6970 to justify the extra cost.

Why not go Sandy Bridge? The Core i5 2500K is very reasonably priced and performs extremely well. I wouldn't recommend a Core i7 2600K unless you truly need hyper-threading for intense multi-threaded apps.

Honestly, I went from a Q6600@3.0GHz and a 6950 to an i7 950 and 2 6950's. The improvement in games was minimal from the Q to the i7. If you clock the Q higher than stock, you won't notice a lot of difference in games alone. If you are encoding or doing anything CPU intensive, you will notice differences.

If you have the money, however, go ahead and make a new build.
If you have a microcenter around, 950's are $199. Combined with all the x58 stuff being sold on OCN, you can have a Nehalem system for fairly cheap... even cheaper than a SB system.

If you can wait it out, I'd stick with the Q until later this year when intel announces the new Enthusiast platform and chips. If you don't want to wait, or don't care about the newer stuff... Go for it

6950's are awesome bang for the buck cards, and very powerful. I'd get the reference model 2GB so you can unlock the shaders. The price difference between the 6950 and 6970 do not justify the minimal performance gain. The 6950 is the sweet spot right now.

I don't see me utilizing the hyper-threading as much as I originally thought on this PC. I'm going specifically for a GAMING rig so is the i5 Sandy Bridge my best option?

Yes. Unless you need the extra cache or HT, the i5 is the better buy.

2500K is a great option. Not worth paying extra for features you're not going to take advantage of.

The i5 2500K was more than enough for me. I only went from i5 2500K to i7 2600K because of a trade I couldn't pass up.
