I have Zotac's GTX 670 Amp! in an original package that I haven't opened yet. I bought it for 229€ (311$) in a sale. I can return it and get my money back.
So I spotted Gigabyte's GTX 670 Windforce 4GB GDDR5 in a sale for 259€ (352$) and I wonder if I should return my Zotac and get the Gigabyte's GTX 670 which has 4GB of memory. So is having 4GB graphics card much better than having a 2GB? Is it necessary to have 4GB of memory and is it in my case worth the extra hassle and 30€? I heard also that Zotac is more powerful but Gigabyte has better cooling.
