How bad would it be if I was to get the GIGABYTE Radeon 7850? I think the keyboard is way over my budget. Would about $50 be enough for a decent one?
It's a high tier card, you'd be getting close to maxing out most games if the goal is maintaining >30FPS. Getting 60FPS with no noticeable drop in image quality should be easily manageable if you spend some time customizing the graphical settings for each game.
If you need a cheaper keyboard:
I'm using a microsoft comfort curve 2000.
Now you might say, "microsoft? Keyboard? They can barely make an OS!". Let me tell you something. This is the best damn keyboard I have ever used. It lets virtually any key combination through correctly. It's not NKRO (I can't press Rshift Lshift X), but I can press more than 6 keys at a time, which is supposed to be the limiting factor in USB (USB only allows 6, but the keyboard sends it through in multiple polls). There are 10 extra keys (volume, back, etc...) which can be assigned macros. There's even a calculator button above the numpad, which is immensely useful for me.
The keys are rubber dome, but they're slim, and scissor switch.
I got it for free, but it costs $15-$20 new.
Also, my first video card burnt out. How can I prevent this problem in the future? I don't want to spend $$$ and have the new video turn into trash.
Monitor temperatures regularly with things like
HWMonitor, I suppose. There are warranties on these cards so you're at least insured from early failures.
By the way, why not 560ti?
560Ti as well as the 560Ti 448 core edition get
severely outperformed by the cheaper Radeon 7850. Not to mention you'll have the additional VRAM for games that need more than 1GB.
There's this "category special" on this
XFX 7850 that ends today. It's $240 at the moment.
None.
