Phenom II x840 Oced to 4.0 bottle neck to crossfire 6850?

[Zac418]

Hello, i was wondering if that would be a bottle neck, the 840 is oced to 4.0, and was thinking about getting another 6850, or a phenom II x6 instead, with just a 6850. What do you guys think?

Hello Zac418;

What resolution are you gaming on? That will some impact on how well things balance out.
What games are you running?

I once ran my HD 6950 on a stock (but unlocked) Phenom II X3 720BE & was doing around 25-35fps on Crysis 2 and 2nd highest setting at 5760x1080. I bought another HD 6950 for CF & got 50-60fps so I guess even the stock 4 core 720BE still have a lot more to give. The Phenom II x840 oced to 4.0 should do better (I guess the high OC should compensate for the lack of L3 cache).

Im thinking @ 1366x768 the X4 840 @ 4GHz & Radeon HD 6850 is pretty well balanced.
You're probably getting 50+ FPS with no AA? and 40-FPS with Post-Process & 4xMSAA?

In BF3 there is an AMD issue when you try and run Post-Process & MSAA

Yeah i get about that. I got a .cfg that boosted the fps and get about 30-40 fps on ultra. So do you think if i got another 6850 it would still be balance? I just want 50-60 fps on ultra

2nd HD 6850 should help you reach that goal. A CPU upgrade with Phenom II x6 would not.
Checkout the Crossfire scaling from the THG article in that link above.

Okay thanks for the help! I'll be buying another 6850 soon.
