Upgrading my computer. Need new CPU, Mobo, and Ram. Currently own one 4gb MSI RX 580 Armor, and wanting to buy a 2nd one. My thoughts are, the ideal computer would be a coffee-lake i5 with crossfire 580s, however I only have less than $400 to spend right now. Figured I can either get an i5-8400 and hold off on the crossfire. Or I can get crossfire now and pair it with an Athlon X4 950 until I have enough to upgrade to a Ryzen 1600 or better.

Any thoughts? At 1080p, anyone have any clue how much that Athlon would bottle neck crossfire 580s in games such as Crysis 3, Project Cars 2, Rise of the Tomb Raider, and Battlefield 1?

Massive Bottleneck.

I previously had an AMD Phenom II X6 1100T which in some games (like the first Project Cars) was a bottleneck with ONE RX 480. And that processor is significantly faster than yours.

Prior to that I had Crossfire R9 280's, and the other thing I will say, Crossfire sucks. You need a huge PSU, not every game supports it, it was glitchy, micro stutter, and many other problems. You're far better served with a CPU upgrade than to buy another RX 580, it will be a disappointment.

Thank you for your input. Going off of sites such as userbenchmark.com, my current CPU (i5-4570) is only a hair less powerful per core than Ryzen's offerings. So shouldn't be much of a bottle neck for games that don't use a plethora of cores? - Hoping. I found a MoBo that supports crossfire on ebay for very cheap, and am going to try that. If it provides me with some headaches to run CF, then so be it. Will be worth it just for the joy of fiddling with my rig from a hobby perspective
