TRIM is designed to keep your drive's performace at its peak level throughout its useful life. Not having TRIM will lower the drive's performance very slowly, over time. No one knows *exactly* how much and by how fast your drive will deteriorate. Many modern SSD's have built in garbage collection that is a form of TRIM built into the SSD's controller. Manufacturer's claim it works just as well as TRIM - maybe or maybe not. In all honesty, its a bit too fuzzy to tell.
Chances are, by the time the lack of TRIM will be even a small issue, you're probably ready to dump that drive for something newer, faster, and cheaper, since it'll take years to affect you.
Having said that, SSD caching is specifically designed for people with small drives to get "SSD-like" performance along with their larger disk drives. A 120 GB drive should work just fine for install Windows, your apps, and maybe 3 or 4 of your more played titles without issues.
You will get far more performance, i think, having that SSD as a primary drive than as a cache - regardless of the TRIM.
