So i'm stuck with these two choices. These two is the cheapest 280x and 280 i could find. The 280x is priced at 194$ and the 280 is 172$. I know the difference is just the stream processors. Is it worth it just to grab the 280x for more future proof since i probably going to use the gpu until the end of it's life. Or just grab the 280 because there isn't much difference? Im using a 1366x768 monitor.
