Greetings, folks!
So, the graphics card (GeForce 530) that came with my computer was weak to begin with, but lately it has really started to bugger me; it can't run even WoW above 25 fps with decent graphics. Plus I'll be needing good performance for my studies and work, which involves lots of CAD stuff (SolidWorks etc.). The computer's i7 CPU itself is quite powerful, and there's more than enough memory, but its graphics desperately need upgrading. I'm not looking to custom build a computer from scratch; I just need to upgrade an existing one that's otherwise good.
Unfortunately I'm far from a computer hardware expert myself. All those names and model numbers tell me absolutely nothing, and I would appreciate opinions from actual users instead of just the manufacturers or salespersons; so I need to resort to asking advice from forums.
So, my most humble request: I would be grateful if someone could recommend a good graphics card for a typical Windows 7 tabletop PC, with a budget limit of 150-200 $/€, for both gaming and working.
PS. no ideological rants about Windows, PC vs. Mac, Explorer, min-maxing performance or other stuff, please; just the graphics card.
