Sorry, but that question has been tossed out too many times.
As to item 2, google like this. NOTEBOOKCHECK GT 630M and you find that chips benchmark. Alter it to the 7730m and compare. Just a little work for you.
About RAM. 4 to 16GB is fine for most things. Disk space is rather an odd question. My work machine has 120GB, the travel laptop is only 500GB and is half or more empty so it appears that space is what you make of it.
I'm buying a new laptop for general school use and maybe some casual gaming like tekkit and stuff. im comparing mainly dell and hp, and i had some questions about their specs
1.Dell with an i5 processor and AMD Radeon 7730m, with 6 GB RAM or HP with i7 and intel HD 4000, with 8 GB RAM
2.How good is Intel HD 4000, NVIDIA Geforce GT 630m, and AMD Radeon 7730m compared to each other?
3.How much RAM is good for high end gaming, just so I can get a perspective?
4.What is your recommended hard drive space for a laptop?
