Hi everyone,

I've had some help on the forum already regarding part picking and the advice was really useful, I'm getting down to the finer details now and would appreciate some help regarding GPU's and RAM.

My Build: http://uk.pcpartpicker.com/list/psmzxY

CPU - AMD Ryzen 5 1500X 3.5GHz (£170)
CPU Cooler - AMD Wraith Spire Cooler (Stock)
Motherboard - MSI B350 Tomahawk ATX (£100)

Storage - Seagate Barracuda 2TB 3.5" 7200RPM HDD (£60)
Storage (OS) - Sandisk SSD PLUS 120GB 2.5" SSD (£48)
Video Card - Gigabyte Radeon RX 570 4GB (£168)
Case - Corsair SPEC-ALPHA (Black (£65)
Power Supply - Corsair RMx 850W 80+ Fully Modular (£109)

Overclocking GPUs
I was wondering how much extra power is required if I plan to overclock my GPU. I have heard some people say an extra 150W but that sounds quite a lot, especially if I plan on adding a second GPU in crossfire.

Crossfire Support
Are all GPUs compatible for crossfire support, providing you use two identical graphics cards? Also I'm split between RX 480, 570 and 580; if I'm building on a budget will the 570 be sufficient for 1080 60fps?

Cheers, PT.

Hello.
Yes the rx 570 is pretty good for 1080p 60 fps but crossfire isnt very useful if you are not and editor or have programs which benefit from multiple GPUs. i would rather pickup a stronger gpu than going crossfire. And no it wont eat that much, it will usually eat 20 to 30 % of the power consumption even with 2 rx 570 you would have a lot of headroom for overclocking with that PSU. And rx 580 would give you the best performance. But if you would have money for a gtx 1060 i would buy that instead of doing crossfire for SURE.
