500gb HDD + 60gb SSD /or/ 1tb HDD?

So either a WD Caviar Blue 500gb hard drive with a 60gb OCZ Agility SSD.

OR

A 1tb Caviar Blue hard drive.



I will be using the computer as my only computer and I will gaming a lot on it. Planning on playing high end games, but I don't buy a lot of games as I don't have a job. I don't see any videos or music being stored on it. Maybe like 100 photos (that's a stretch).

The first option is a little more expensive, but I really want my OS on a SSD! Also Steam would be really nice on one as well.

Guess I'll put the rest of the system:
Case - Cooler Master Elite 430
Power Supply - NZXT Hale82 modular bronze certified
RAM - Patriot 8gb DDR3 1333mhz 2x4gb
Motherboard - Gigabyte H77 mATX
DVD drive

Parts that I don't own yet:
i5-3450
Geforce GTX660  
Windows 7 64bit
