Hello, In the near future I will be purchasing a new processor (Amd Phenom II X4 975) but once I install the processor into my computer I will still have a Amd Radeon HD 6450 gpu which I will be upgrading a few months later, so im just wondering will there be any bottle necking that could occur with that cpu and gpu in at the same time and if there is will it affect performance.

There is always some bottleneck somewhere.
However, this wont mean there is an issue. The 975 will run fine with the 6450, and vice versa.

When you are planning games, the limiting factor for your FPS performance will be your graphics card, as that CPU you have is a higher performance part than that graphics card. The worry about bottleneck should be when you buy a new graphics card, but as long as you don't go into the super high end you shouldn't have an issue with bottleneck.

The graphics card im planning to buy is a Amd R7 265 2gb gddr5, So I think I wont have a problem.

No problem there. A 965@4GHz can support up to a GTX 760 (Thats what I'm running), so your 975 would be almost the same.

yup you will be fine everything will work well. Anything higher and it would be getting risky. Gam3r01 says his GTX 760 doesn't get bottlenecked by a little bit faster CPU but I would say that its on the edge that even a mild overclock on the GPU would end up showing signs of some bottleneck.

However that GPU is higher end, so you won't have any issue even with a heavy overclock on the R7 265

I agree here, I dont think any core/memory speed increased would still be un-bottlenecked.

My 965 at 3.9 doesn't bottleneck my 7970 at pcie 2.0 x8, unless u count 99% GPU usage as a 1% bottleneck lol. It does touch 100% often. I'm actually super relieved the 965 could fully push the 7970. Still planning to hand it down and trade up tho ;)

Its dependent on what you play too though. Sounds like you have had excellent performance so far but some games such as Watch Dogs or other CPU intense games would give you a very significant bottleneck. So really bottleneck is a very relative meaning in that there are many variables that need to be considered.

I'd be lying though if I didn't say I'm a little jealous of you Phenom II people. That has been one of the longest standing high performance CPUs ever and you definitely get your moneys worth when a product is able to be used longer. I'm hoping my i7 fairs the same, but there is no way to know yet.

I'm hoping the i7 4790k i plan to get soon fares the same too lol. The 965 didn't balk at watchdogs, but to be fair I didn't play it much. I played (finished a few days ago) Dead Rising 3. Depending on the overclock profile, sometimes I got a stutter at 1080p max settings, surrounded by 100s of zombies killing 20-30 at a time from turret vehicle. But after the first few minutes it was smooth. Except other times, when there were like 1-2 second lags every 5 seconds lol. But i was screwing with my settings alot. If I left it at a trusted profile, I usually never saw a stutter (after first minute).
While it shreds, my 965 needs stupid high voltages, like I'm talking 1.4, ya freakin 1.4. Wasn't the pick of the litter chip, but for it's faults, it still holds it's own :)  Maybe it was a lucky grab, just not traditionally what ppl think is would be one lol. I mean it OCs to 3.9 on OC genie lite, I don't even bother to try (shame on me I know).

Fact remains that the fancy C3 mem controller is still limited to 1333mhz :fou:
