Getting 7950 , possible bottlenecks ?

post #1 of 25
Thread Starter 
I was thinking much about all this stuff and finally i voted for HD 7950 from MSI. I have i5-750 OC'ed to 3,4 GHz. Are some bottlenecks possible ? I mean im going to play some games on Full HD 1920X1080. And is HD 7970 so much powerful than HD 7950 ?

7950 will be the best bang for your buck, and more than enough for 1080P - only get the 7970 if you feel like spending the extra money, it's not at all necessary for that resolution.

The i5 750 at 3.4 shouldn't be much of a bottleneck at all - but you could just overclock it some more - then I'm sure you'd see a few extra frames when paired with the 7950 thumb.gif

What's stopping you from pushing the CPU further?

Also, maybe consider another 4GB of RAM - some of the newer games might appreciate it.

I don't see much of a bottleneck, if any at all. You should be good to go.

Yea and im getting 8 gigs of ram too wink.gif So i will try to push it bit more like 3,8 and we will see

Yea and im angry because when i try to overclock over 3,4 the system is very unstable and i cant find good voltages. I know it takes time to find but i was trying 5 hours and still cant find good settings.

Well , keep trying

For 1080P gaming, you could go with the MSI R7850 Power Edition, the 7950 would be overkill for that resolution and would probably be bottlenecked down to 7850 performance.
Fortissimo

Well , keep trying

Finding the right voltages is very easy if you overclock properly... follow some of the guides here on OCN and 3.8 GHz shouldn't be too hard to attain.

When you OC, you need to isolate the component which you are testing - never overclock and test more than one component at a time, that way when the system fails, you know at what point the PC needed more voltage, and to exactly which component. Adding voltage should and will never be a guessing game if you OC in the correct sequence.

Let me know if you need a link to some good guides, or some help getting to 3.8 GHz+ and also don't forget to overclock that Northbridge as high as it will let you go - it will make for very big gains in CPU performance, specifically in the area of gaming. smile.gif

Finding my final max stable 24/7 OC in my sig took me about a full week of testing, maybe a little more. It's not going to be easy, it will be worth the free performance. Luckily most of the time is not spent in front of the PC, just testing for stability after each change.

IMO a single HD7950 is just perfect for a single 60hz 1080p screen and not overkill at all.
