I thought maybe get one now so when I make the jump to higher res il be ok,I just got a feeling I'm gonna kick myself if I don't a second one up at £439.
You wont be needing such GPU power until you upgrade to a 4K monitor. When you do, a more powerful and efficient card will be available at the same price point or cheaper. I advise you to wait, and fight against any temptation to splash the cash.
