Upgrade? Nvidia vs AMD

yeh 120hz screens are nice i love my samsung sa700.

Would never go back to a 60hz. TBH there probably isn't much point upgrading a 6850 CF setup if not getting a 120hz monitor.

I should think that 6850's in CF would get more than 60fps in most games out there.

Well thats the problem, even at 1680x1050 it struggles with bf3 and some other high end games, so itl be even worse going to 1080 as ill lose fps :/ was gonna get a 7950 then just a normal 24" 2ms response monitor?
 
Would i be better of with a sapphire 7950 with these specs:

Features:-
- Core Clock: 810MHz
- Memory: 3072MB GDDR5
- Memory Clock: 5000MHz (Effective)
- Memory Interface: 384-Bit
- Processing Cores: 1792
- Bus Type: PCI-Express 3.0
- Display Connectors: 1x Dual Link DVI, 1x HDMI & 2x Mini-DisplayPort
- HDCP Capable
- DirectX 11 Support
- OpenGL 3.2 Support
- ATI CrossFire Ready
- ATI Eyefinity Technology
- ATI Avivo HD
- ATI Stream Technology
- ATI HD3D Technology
- Warranty: 2 Years

Or an MSI Overclocked radeon 7950 with these specs:

28 nm SLI Type: N/A
Cores: 1792 Multi Monitor:
Core Clock: 830 MHz
HDCP Ready:
Yes
Boost Clock: N/A Width: Dual Slot
Shader Clock: N/A
CrossFire:
Yes
Memory: 3GB
Crossfire Type:
Memory Bit Rate: 384 Bit Low Profile Compatible:
No
Memory Type: GDDR5 Low Profile Support: N/A
Memory Clock: 5000 MHz Package Type: Retail
Cooling: Fan
Maximum GPU Power:
Interface: PCIe 3.0 (x16)


Theres a £10 difference, just not sure which is best :)

In that case unless you have plan for upgrading the CPU as well, I would advise against going 120Hz monitor, as AMD CPU simply doesn't have what it takes to push frame rate once step toward the 60-120fps territory...and will have lots of frame rate ups and down between 30-120fps, comparing to Intel at around 80-120fps when graphic card is not the limitation.

Well i was thinking about buying a 7950, then eventually the 120hz monitor then mobo/cpu upgrade, what would be the cheapest cpu upgrade for me? to get as much use out of the 7950/120hz monitor?

Honestly though...while the 7950 should be smoother overall than using CF6850, but I don't think it would be a huge leap forward. What sort of performance issue you are having with your CF6850 anyway? Driver? Game performance? Micro-shuttering? In BF3 the CF6850 might suffer a bit if you use 4xAA, but if you drop it 2x or even 0x, you should see much better performance.

Well, its just that i only get around 40 -60 fps on bf3 etc, and when recording it drops stupidly, and especially moving up to 1080p im not gonna have enough vram

Have you check what are the GPU usages are like when it drop to around 40fps? Cause if you are talking about playing online on 64 players server, it might not be the issue with your CF6850.

To be honest if you are suffer performance issue with a CF6850 at 1680 res, I would probably blame the CPU...I recall people saying their had overall higher minimum frame rate on BF3 when playing online, after upgrading from the Phenom II X6 at 4.0GHz to Intel i5 using the exact same graphic set-up.
