Hello, I'm looking to upgrade my family PC as I don't have the cash to fully build my own ATM (but plan to in the next year). I think this should be fine but just want to check.

Current set up:
CPU: AMD FX-4300 Quad-Core 3.8Ghz
Motherboard: Asus M5A78L-M LX V2
PSU: Sun Pro ATX-580WA
RAM: GeIL 4GB Single DDR3 Dragon C9 1333MHz
Graphics Card: Radeon HD 5450

Not that Great :(

I think Ive decided to replace the Radeon HD 5450 with EVGA GeForce GTX 770 Sc w/ ACX cooler 2GB. Because of this I'll also replace the SunPro as I know its very bad with probably a Seasonic M12II-750 BRONZE ATX 750 Power Supply, as I dont want anything to damage the 770.

My main concerns are that here http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-770/specifications it says i need a PCIe 3.0 where as my Motherboard only has one PCIe 2.0 slot. The other thing I want to check is will the PSU be able to support all this + a couple of Hard Drives.

I'll also be buying these from the US as it's alot cheaper then here in Australia and relise I will need a power adaptor for the PSU, will there be any other complications with this?

I'd also love your opinions on the choices I've made, keeping in mind I will use these parts in the future when I can afford the other stuff.

Thanks for your help.

Firstly, the power supply is more than adequate for that graphics card + your current components, and should be fine to carry over into your new build when you decide to go for it.

The graphics card will run fine in a PCI Express 2.0 slot, and the performance decrease won't be noticable as your other components will bottleneck the card before the slower PCI bus comes into play.

Your graphics card is definitely the weakest component of your current build, so you should see a substantial performance boost, despite the bottlenecking from your CPU.

Yeah, your will bottleneck 4300 with 770. I would go for a more balance upgrade with 6300 + 270 combo an will probably cost similar to 770. You would also need 8 gb of ram or that will be a bottleneck as well. As for PCIE, 3.0 cards will work on 2.0 motherboards as its backwards compatible.

I will probably upgrade the CPU next along with the RAM but don't want to be buying a second graphics card in the near future so have gone with the higher end 770. I've looked at benchmarks and this CPU despite not great can still run stuff like BF4. How much will it bottleneck the preformance?

I would say it will make your 770 perform like gtx 660 making it a unbalance upgrade. I would say go for 270/660 and get 8 gb ram. The 8 gb is almost mandatory for 1080p gaming, I would address that as lag will make others parts spike in usage unnecessarily. BF4 is very demanding, both gpu and cpu wise (it puts my i5 4670k to work very hard),
