Hi. I am about to drop some cash on a small setup. I was going to get the Sapphire R9 290X Tri-X OC which is about £448 in the UK. Since I am relatively poor I need something that is going to get me a good hash rate with lowest power use. Enough to still be profitable on stuff like Doge etc.

Should I go for this card or a 280x/290 (brands and models please)? 2 perhaps if cheap enough? I am also getting a 1000w brand name PSU so that needs to be taken into account too.

I will probably be buying tomorrow so need an answer ASAP.

Thanks.
