Will My CPU be a Bottleneck for CrossfireX? - Page 3

post #21 of 32
There will be a bottleneck, but it gets lower the higher you oc your cpu. Also the bottleneck occurs after 60 fps, so it really doesn't matter. If you have the extra money, it's good to get a new cpu and motherboard, but that can be pretty expensive. For me at least, I see no need to upgrade yet.

Overclock it to around 3.8-4.0 GHz. You should be okay. The only games that are really bottlenecked by that CPU would be StarCraft 2 and Civilization V.

When you want to upgrade, get Bulldozer or whatever Intel CPU is out.

Well I will get a new CPU in the future; not sure if I'd get a Bulldozer or i7. I've always liked AMD because they seem like better bang for your buck, but I don't want to get into a AMD vs. Intel debate.

For now though the only thing I can do is overclock, but I have no idea how, and I don't have the money to replace a fried mobo or CPU, so I would need a lot of help.

http://www.overclock.net/amd-general...ing-guide.html This guide should help you. It will just take some time to learn.

My CPU and mobo won't be fried right? Also, my friend will probably trying to overclock his at the same time.

Should bottleneck if you don't push that card past 4.5

It won't fry if you take your time and learn it right. The only real danger is using too much voltage or letting the temperature get too high. To start with, you can use a program called hardware monitor to watch temps.

Over clock as best as you can using that guide discussed earlier, it will minimize your 'Bottle', 3.7+ is a good start.
XD_1771 is right that 1333 DDR3 will hold you back a bit.

Unless your bottleneck is limiting your cards to 55% all the time, you should see more fps than a single 6950.

Yes Sandys are a bit pricy, but the are the current leader in most benchmarks, they are also insanely easy to overclock ("even grandmah can do it" was said in the ad), I think it's too easy.
As for the integrated graphics, it's there for normal computing and Intel would have know that AMD was going down the APU path so ticked that box for those reasons.

I think turning a $100 CPU into something that rivals a CPU that costs double is one of the more fun (and challengeing) things to do with overclocking.

I know it's probably hard to tell, but judging by my current system parts, what do you think is probably the max I could overclock to (I am shooting for at least 3.6GHz).

EDIT: Also, with two cards in Crossfire, do you think I should install the second fan on the top of my HAF X, or change my fan configuration at all?

You should be able to get to 3.6ghz easy with that chip, but I think your ram will stop you. I cant overclock my ram much.
