Maybe look around for a second hand gaming gpu? An enthusiast gamer friend of mine updates his gpu quite often and I byu his old ones when I need another Something like a gtx560ti should be well within your budget, I just tried counter-strike source at full hd with that card and got +60 fps.

No, if you're transferring from Mün orbit to Kerbin orbit because you'll need every bit as much delta v to circularize around Kerbin as it cost you earlier to leave Kerbin orbit. You'll need less delta v only if you either aerobrake or go down like a missile without intent to orbit, you see, these values are for transferring from orbit of one body to orbit of another body.
