I've kind of gotten out of PC gaming having gone the way of the console. As a result ive totally neglected my pc. So recently I upgraded my monitor, Samsung U3R2592 @ 3840 x 2160 60hz. And I was thinking of buying the Saphire RX vega 64 Nitro (it was £300 last night and today its gone up to £359.99) But my question is will the rest of my pc drag it down. Ive a i5-4670 cpu and a MSI B45 G83 mobo, 8 gig crucial ddr3 1600mhz. power wise ive Enermax liberty 620watt. Is it pointless upgrading the gpu to vega 64?
