7850 vs 7870 £30 worth it??



the 660ti is too expensive atm as i only see 660ti's prices at £240+, i can only just afford the cheapest coolers with my budget.

i am just wondering would the better cooler and lower price and also lower power of the 7850 be a better investment over the slightly more expensive 7870 that runs faster but uses more power and has a worse cooler?
