My dad got a huge computer about 2-4 years ago for $900+. It started out as a Windows XP, it's been wiped twice and then converted to a Windows 7 about a year ago.
Still runs programs fine but:
Blockland = 30 FPS
Minecraft = 24 FPS
Blockland + Fraps = 12-14 FPS
Minecraft + Fraps = 6 FPS
I don't know where all this 70 FPS bullstuff has been coming from for the past 8 years of my life but I think its stupid.
