FX-6100 Bottlenecking GTX 680 FTW?

Last response: in Graphics & Displays
Share

I'm kinda new to graphics cards and such, and I bought a GTX 680 FTW (4gb) for better performance over my GTX 560 (2gb) and I ran the Unigen Heaven DX11 benchmarking tool with my friend who has the GTX 670 (2gb) and I noticed that he had significantly better scores than me and I was wondering how that was possible when we had the same settings.. The only thing I can think of is that his CPU is better than mine and mine is possibly bottlenecking the GPU.

CPU: AMD FX-6100 6 Core @ ~3.3 GHz
GPU: EVGA GTX 680 4gb
Ram: 8gb
OS: Windows 7 64 bit

If I left out any information let me know.

I was running the same processor as you with the same card :D  I had bottlenecking issues even when I OC'D the CPU to 4Ghz+.

I gave up in the end and bought a new mobo/CPU and no more bottlenecks. I upgraded to an I5 3570K good CPU for gaming. Just got my new PSU today to power it all, 850w.

No regrets.

4GB cards are mainly for multi Display and uber high resolutions, what res are you running at?

I'm running at 1600x900 resolution, I do have 2 monitors, but I'm getting a 3rd one soon for gaming.

Also, you mentioned that the i5 3570K was good for gaming, but would a i7 3930K be better? I was thinking about getting an X79 chipset mobo to run it, but I'm not sure if it's even all that better.

Thanks.

Oh wow yeah you're bottlenecking at 1600x900... you'd still be bottlenecking at 1080p but not quite as badly.

The 3930k isn't much better for gaming than the 3570k... 5% better at most, and that's probably generous. It's not worth the price premium if gaming is your primary purpose.

The difference between the I5 3570K and the I7 3930K in terms of gaming is like a couple of frames, you would save alot by taking the I5. I7 doesn't give much of a benefit over the I5 for games, you can always OC the I5 anyway.

I originally thought of getting the I7, but I didn't see the point in spending nearly £100 more for a few extra frames that aren't needed. All the games I throw at my system runs maxed out/graphical mods etc all buttery smooth and I'm happy with it. Skyrim, Battlefield 3, Shogun total war 2 etc and that's on stock clock @ 3.4Ghz with the GTX 680, I bought the MSI one, Twin Frozr 4Gb. The board I use is a Gigabyte Z77-DS3H and 850w, happy with how it performs.



You're welcome.

I think you're thinking of the 3770k... the 3930k is a lot more than $100 more than a 3570k !!

If the 3930k were just $100 more, then it would absolutely be worth the purchase. But it's twice as expensive... and moreso once you include the increased platform cost for X79 over Z77.

Here the price difference of I5 3570k and I7 3770k is like £50 more and the 3930k 100 to 200,. Pounds not dollars :D .
There are so many numbers with and without "K" it's common to get confused xD.

What motherboard would be good for the i5 3570K and not too wallet hungry?

Also, I've never really done any overclocking before, so what would I need to do that? Is it something in the BIOS, or do I need some 3rd party software?

I also have a 700W (or 750W) PSU. Do you think that would work fine for all this?

Also, would I be able to use my old GTX 560 for SLI? What would I need for that? Any hardware, or is it just all software stuff?

You can't SLI a 560 with a 680 (you can only SLI like cards) but you could put it in your rig as a PhysX card if you don't want to sell it.

Overclocking should be done from the BIOS. Head over to the overclocking section of these forums and there are guides. It's pretty simple to do basic overclocking, though - you just increase your CPU multiplier. It only gets complicated when you mess with voltages and try to get a big OC.

You'll need a decent motherboard and a 3rd party CPU heatsink. I'd recommend the Cooler Master Hyper 212 Evo if you're on a budget, or the Noctua NH-D14 if you aren't (and if your case has the space).

As for a motherboard, I'd recommend the ASRock Z77 Extreme4 if you're looking for a solid but not pricey board.

What is the make/model of your PSU? Wattage doesn't tell very much about a PSU, and you'll want a good quality unit for overclocking.

What is ur score?I mean average FPS.Kinda interested.


My average FPS was around 40-50 usually high 40's on highest settings everything on 1600x900 resolution. My friend was testing this with his setup and he was getting an average 60+ FPS with his 670, which was why I was confused.

A stock gtx 670 get around 54 fps in heaven max at ur res.I get that.My GTX 670 is stock speed.Is your friend's gtx 670 OC?8XAA,extreme tessleation.


He just re-ran the test and got what you said (54 fps) at stock speed. I ran through it at maximum overclock (what my system can handle without shitting out) and got 55 fps.

That's not a great power supply if you're wanting to overclock IMO:

I'd recommend taking a look at something like the Corsair HX750 which is just over $100 with promo code + rebate right now:

Even the HX650 would be fine:

The ASRock z77 extreme4 is an ATX board so you just need a case that would fit that. They make an equivalent board in mATX form factor if you have a smaller case and can only fit a micro ATX board (the Z77 Extreme4-M).

Your case needs to be at least 160mm wide for the Hyper 212 Evo to fit, I believe.

And bear in mind that I'm working from USA pricing data... it's possible that something which is a good deal here is not in the UK.
