Hello everyone,

I'm new here and could do with some of your vast knowledge when it comes to PC hardware. Now I built my PC a good few years ago and haven't exactly upgraded that much on it, though I haven't really needed to. The only upgrade I have made is the GPU and of course the OS. Anyway, I was looking into possibly giving my system an upgrade of sorts though having not been following hardware for a good few years I wasn't sure where to start. First of all let me detail my system:

Motherboard: Asus P6TD.
PSU: Corsair AX760.
GPU: Asus AMD Matrix 7970.
CPU: Intel i7 920 (Overclocked to 3.80).
RAM: 6GB Corsair TR3X6G1600C7D Dominator).
CPU Cooler: Titan Fenrir.
OS: Windows 10 Professional 64bit.
Case: Antec 1200.

So I certainly feel like something is potentially bottle-necking my system on some more modern games, which considering its age shouldn't be surprising. I wanted to know what might be causing this bottleneck and what I might be able to upgrade to help with this or if it at all might be related to my recent realization that my motherboard supports PCI-E 2.0 but my GPU can run on PCI-E 3.0, would this potentially be causing some problems for me.

If this is the case might it be worth upgrading my motherboard (if so, any recommendations) or is there another issue I'm not seeing, this is why I decided to ask much more knowledgeable people who know what they're talking about.

Your help would be hugely appreciated.
Thanks.

Hi CountMike,

Thanks for the tip. So I've been doing some testing and I was a little surprised to find that by using MSI Afterburner and HWiNFO, the GPU D3D usage appears to reach near 100 percent when trying a few different games. Now that's running on max settings and the framerate drop is noticeable but I was convinced it was an issue with my RAM for a while there.

I'll continue some tests but do you have any advice? I have been looking at some GPU's but a lot of folks don't recommend an upgrade from the 7970 yet. I play at 1080p and would love to run games at max but there doesn't appear to be a clear upgrade path. I would probably prefer to return to an Nvidia card as I just don't have much faith in AMD and their driver support these days.

I had been looking at the Nvidia GTX 970 though from what I've read people seem to indicate they're somewhat similar cards.

Interesting to hear CountMike, I didn't realize they're drivers fare better than Nvidia on W10. They have improved some over the years, they were terrible when I got my first AMD card some years back.

I have the Asus Matrix HD7970 Platinum card which I believe features 3GB.

Thanks again.
