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
OS: Windows 7 64 bit
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 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.
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.
