But does a single 290X make sense at 1440P? Okay You might be a lot better at meeting those VRAM requirements, but if you can only hit 40fps then I'm not sure thats what I'm after.
I'm not sure what you mean. The 290X / GTX 980 are the best single GPU's from AMD and Nvidia. If a 290X isn't good enough for you than you only have one other choice Nvidia or go dual GPU's.
In both scenarios single or dual you're still better off with more vram as even some current games use more than 4GB at 1080P. Future games even more so. Why not get a twice the vram for £30 - £40 more..
The same guys that are currently saying 4GB is enough, would not be doing so if Nvidia had a cheap 8GB card. They would be buying that to have extra in the tank. It just so happens that AMD have a high end cheap GPU with 8GB 'extra in the tank', but it will largely be ignored until Nvidia introduce a similarly priced card with more memory. Then people will be saying that more than 4GB is recommend.
Just wait and see if Nvidia release an 8GB card, and watch how many people suddenly say more vram is recommended. There are those that follow and those that lead
Pay an extra little bit of money for something that is already cheap and have in the tank now just in case. 8GB 290X makes total sense over the 4GB version, at today's pricing it's a steal !!
