This description will be short as not much changed from my other builds and it explains the in detail.
GPU MSI Radeon RX 480 Gaming x edition 8gb (crossfire).
The graphics have had a big upgrade for a major performance gains I was actually shocked at the levels of performance they gave me.
For the past couple of weeks I was back and forth on how to upgrade the graphics in this pc. The choice was between the GTX 1080,1070 or a pair of RX 480's. Here in the UK the 1080 that I wanted would of been close to £700 and I couldn't justify that amount of money so it came down to the 1070 MSI gaming z which was on offer and the 480's. The deciding factor was my monitor was a freesync monitor plus I've been AMD all my pc gaming life and really didn't want to change yet. At this point i'm glad I went this way this by far is the most powerfull pc I've ever built I think the only reason that I couldn't get a 4k score in Firestrike is the CPU been i5 not the i7 there might be a bit more to be had out these cards yet.
The overall verdict on the RX480
These cards do run hotter than expected but I suppose its to be expected in any multi GPU setup but they are quite under load and the performance as explained before shocked me. I really want to put these cards under water cooling so in the coming weeks I'm going to hunt out some water blocks for them to sort out the temp issues.
