Hey,
It's been a few years since I upgraded my computer a bit; I'd be grateful for some advice regarding graphics cards, SSDs and Windows 10.
I use my computer (4GB RAM, 3GHz Dual core, 500GB HDD) for internet browsing and games mbut am not the kind of enthusiast that needs (or can afford) top-notch stuff.

Graphics cards:
I currently have a Radeon HD 4800 (see picture for specs) and am looking for an upgrade but to a budget kind of card. This is a field I have very litte understanding of and need most assistance.

SSDs:
I understand that different SSDs can perform drastically different, after checking a couple reviews I think I have chosen to get a Corsair Force GS 360GB. I would love to read if anyone here has any specific feedback on this model or subject.

Windows 10:
I am interested in having (for a change) a legal copy of Windows and am tempted to purchase a Windows 10 setup disc with the SSD. I am wondering if anyone knows if prices are expected to drop anytime soon for the new operating system, or if I should just go for it?

Many thanks in advanced to anyone who replies with useful information.
