Sapphire Radeon VAPOR-X R9 270X OC 2gb vs Sapphire Radeon R9 270x 4gb

Hey guys , I was wondering about buying a new video card. So.. i decided to go for R9 270x and i saw these two video cards. The problem is simple which one of them should i pick, like i'm not a fan of overclocking so i don't care a lot about it but it will be nice with these two better coolers. I heard that the 4gb is not so ussed on a single 1080p monitor but i was thinking like 4 gb of vram will work better for a bigger field of view or MSAA or whatever. After a few specs i saw that the Vapor-x 2 gb has some little more improvements on Cpu clock, Gpu clock and memory mhz vs the 4gb.
In final, my problem is simple which one of them should i pick and i'm thinking about the future.
Thanks a lot guys for the attention and reading this thread !!

    Get the 2GB. The 4GB performs no better than the 2. The card is not powerful enough to make use of the extra memory. If you go with the R9 280 3GB, THAT offers some performance benefits. Clearly 4GB is not needed when only 3GB is used on most of the 280's.

    O yeah.. and by the way the video card that i wanted to change is an old sapphire radeon hd 6870 and i was wondering if i have to change something like the psu (is ok 500W i think) for the r9 270x
  4. Older cards have different power requirements than some newer ones. The HD 6870 called for a 500w PSU with two 6 pin connectors. The R9 270x calls for the same so you should be good in that regard. You might want to consider replacing the PSU though if it's got a lot of miles on it. What is the brand and model number? You want something that's Tier 2B or higher here:
