the 270x is between the 7870 and 7950For a little more than the 7850 Denther mentioned you can get an AMD 270x, which performance wise sits between a 7950 and 7970, but for just less than a 7870 would cost.
I'm going to go with the 7850 then, but there are tons of different versions... Which one should I choose (I'm a complete noob with hardware...). For example there is the 2Go Dual-X OC Edition or the Bulk version...

Go for the cheapest 2GB one from Sapphire or MSI or any good brand like that.
Every Radeon I've owned has been a Sapphire Radeon and I've liked them all. I like EVGA personally for NVIDIA. The other brands which Denther listed for AMD are also good (ASUS, Gigabyte, MSI and HIS).I'm particularly fond of Sapphire (I use their cards myself). But in addition to MSI, Gigabyte and HIS would be good brands, correct?
I think I would also be inclined to wait for the 270X since it will be faster than the 7850. The 7000 series are being discontinued, so it might be best to wait for the new cards.Punk, I would wait for the R7-270X if you can wait a month or two. If you can't, yes a 7850 is a good choice by any of the brands Dent her listed.
I also like Sapphire but most of them are good. Powercolor and Zotac are the "meh" ones I can think of off the top of my head. They're not bad necessarily, but shouldn't be your first choice. MSI, Asus, and Sapphire are generally the best manufacturers for AMD cards.
