Poll about graphics cards (currently have 1 (Matrix) in my computer).
I could go for another Matrix (€350), it would make adjusting the loop relatively easy as the pcb is the same, thus I wouldn't need to adjust so much. Or I could go for another 280x as it has similar performance as the Matrix but costs a lot less (€269), however I must change more in the loop. Or Keep it simple and just the one Matrix.
