How much FPS would i get with those two computers?
It's actually hard to tell... Radeon HD 7730M is roughly 2/4 of the desktop Radeon HD 7730 and Radeon HD 7730 is at the same performance as Radeon HD 6670, so that means it's 2/4 performance of Radeon HD 6670... It will be okay for Minecraft, but for other games not... At the same price (If you want to game) you need a desktop PC, like this one:
ASUS M5A97 R2.0
AMD FX-6300 3.5GHz
Corsair Vengeance 2×4GB DDR3 1600MHz
Sapphire Radeon HD 7870 2GB GDDR5
Zalman Z12 Plus
Western Digital Caviar Blue 1TB
Corsair Builder Series CX600W
If it's over your budget, change 7870 to 7850. Choose whatever solution is best for you.
