Thank you for reply!
So, ideally I would like a quiet, reliable system for ~3 years.
I do not really need more than ~500GB storage memory. Is there actually a point getting HDD?
Yes, I agree that 4GB Video card is a better choice, However should I go for GTX770 or R9 290? As I mentioned I would like a quiet system.
And yes as u said £1000 + peripherals
You'll fill up a 500gb ssd pretty quick. When you format it, you lose 50gb, Windows another 30gb plus a 30gb reserve. So by day one it'll be at less than 400gb. You also then need to make sure it always has 50gb free space to make sure it doesn't crash. So you have 350gb to play with. That's a few tunes and a bit of video.
Look at reviews to choose a card. The Gigabyte 290 is pretty quiet. With 3 fans, they don't have to spin very fast to keep it cool.
