I'll suss out some Benchmarks for stock speed R9 290's and see what I've been getting becauise so far it seems like it hasn't been affecting performance, also in the future i plan on throwing in an unlocked i5 and liquid cooling. But i didn't want to have to upgrade my gpu.
Well considering 700 euros is around 1100 AUD I didn't do that bad, and the 750W PSU was me getting ripped by the salesperson i guess, he kept assuring me I'd need at least a 750W for the 290
Exactly what i was thinking, upgrading to an i5 later is cheaper than upgrading the GPU.
