GPU Recommendation

Help please!
I am choosing between these two:
Sapphire Radeon HD 7850 Dual-X - 1 GB GDDR5 (152,99 €)
and the reference AMD Radeon HD 7850 OEM - 2 GB GDDR5 (169 €)
I will be gaming at 1080p and overclocking (if i get a card w/ a decent cooler). I have an AMD 1090T X6 CPU. Which card do you think is the best bang4buck? I would get the 7870, but i won't be spending more than 170 €...

I dont know the cards, but I would deff go with the Sapphire and the non-refference cooler..!

I've owned many sapphire cards, and my new sapphire 7970 vapor-x is coming in any minute now. Always have had good support, even though I've rarely had to use it. Don't think you can go wrong with the sapphire. 

If those are the only two choices I'd go with the Sapphire. Although I've read that newer games will start to utilize the VRAM more so you might want to go with the 2GB card. If it were me I would shop around for an ASUS Radeon 5970 dual GPU 384-bit x2 card. Those are absolute beasts and you can find them for around 150-200USD on E-bay a lot of times.
