So for an upcoming BBT (Bits Be Trippin) Episode we decided to check out some R7's and see what they could do. These sapphires can be picked up for 35-40 bucks on ebay... for folks with limited power and want to hedge on some doge or other alt coins might be a cheap solution to enter the game.
Machine Build:
MB: ASROCK H81 Pro BTC (57.99) ~ at microcenter if in stock, otherwise 150+ on ebay
CPU: Intel G3220 Haswell (49.99)
MEM: (1) 4gb Cosair Ballistix 1600mhz (37.00)
HD: PNY 120gb SSD (Microcenter for 39.99 after rebate)
Risers: 5x 1x to 16x (any work, happened to get 5 of them for 40 bucks on the bay)
PSU: Corsair CX600 (39.99 microcenter deal)
GPU: Sapphire R7 240's (35 each on ebay) ... OC'd to 950/1000
Total system AC via Killawatt - 248w from wall
Bottom line: 635k/h @ 140w (just cards) for 35x6 = 210 bucks
