Would It be easier to buy a new processor or stick with my 8120, buy a cooler and overclock to prevent a gtx 760 bottleneck?

Hi all, I'm about to buy a Gtx 760, but It just occured to me that my fx-8120 is at the stock speed of 3.1ghz, first of all, would that bottleneck, and if so, what speed do I need to get to to prevent doing so? Also should I buy an aftermarket cooler for overclocking? (I currently have the stock fan) . Or is it easier to buy either an fx-6300 or an fx-8350? (I have no Idea how to overclock in the bios)

there won't be a bottleneck between the two. even at stock. You can however purchase a better cooler and overclock that will help out in just about every scenario (except heat generation) otherwise, you're fine.

I recommend upgrading to the FX6300 or FX8320. The FX8120 is really not very good. If you truly have no interest in overclocking, you can pay a little extra and have AMD do it for you buy getting the FX6350 or FX8350.

If it did bottleneck i doubt it would be all that much and i would not overclock on the stock cooler.

What motherboard do you have? What resolution do you game?

I wouldn't worry about a new processor -- instead of investing in one you could take a leap to a GTX 770, or even a R9 280X (or, gasp, an R9 290).

My motherboard is an asus M5A78l-M/usb3 and I run at 1080p, I could afford a new processor but If its cheaper to overclock and buy a heatsink, then I honestly don't know. are you sure 3.1 ghz won't bottleneck? that seems pretty low.

The FX8120 has a turbo speed of 4ghz but it's still has really weak single core performance and that will hurt you in some games.

I never noticed, most games use more than 1 core but will that be an issue that is worth upgrading over? I do have the hotfix for windows 7 installed btw.

FX 8320, change the multiplier to 20, instant FX 8350 speeds and can be done on stock cooler.

I say get the GTX760 and see how it goes. Maybe you need a stronger cpu, maybe you don't. No need to upgrade unless you need to.

As others have said- keep the 8120 for now, the performance difference between bulldozer and piledriver isn't that big (10 to 15%). If you need more its an unlocked chip so overclocking is realyl simple and you can push it quite a way with better cooling.

Yes but how easy is the overclocking once I've bought a stock cooler and do I need to even overclock it? some people are saying that I don't need to but 3.1ghz seems a bit too low to not bottleneck.

Well you would need to look at a better air cooler however they shouldn't cost you more than about £20. As for overclocking- easiest way is to change settings in the bios. To speed up any FX chip all you need to do is increase the 'cpu multiplier'. However as CTurbo has sated that CPU isn't 3.1 ghz exactly. It runs between 3.1 (minimum) and 4ghz (maximum) speed.

I would only suggest over clocking it if you're actually having a problem running something. The PC I game on most is a first gen Core i5 laptop that runs at 2.4ghz and yet modern games (e.g. Tomb Raider 2013, Star Conflict) run fine. It does depend on what you play- however normally the graphics card will bog down before the cpu becomes much of a problem.
