You are probably right. The Vertex 1 is even slow on my 2500k system. I definitely notice occasional slowdown and "choppiness". But after buying a Vertex 2 which died on me in 2 days, and hearing about all the BSOD and dead Vertex 3 and Corsair Force 3 drivers, I am waiting until 4th generation or something from Intel such as 520.
Still, even when I put my HD6950 into the secondary rig, despite "flash hardware acceleration" touted on AMD's website, I often hit 95-100% CPU usage when watching 1080P content on Gametrailers (game reviews) or YouTube clips. I re-installed the OS twice and I am still hitting 95-100% usage in certain 1080P content. The GPU acceleration is not working for some reason.
That doesn't surprise me (on the 2500k/Vertex system). I had my Vertex in the PC in my sig and it was choppy at times, I spent too many hours in the OCZ forums doing optimizations and working on it as well, it never was right. I had some other OCZ SSDs (Jmicron), which were total garbage (but cheap and I didn't expect them to be so bad).
If you were going to buy a new drive, there's no reason to buy an Intel drive today, at least until they release their native Intel SATA6gb drives. Today I'd buy a Micron C400 drive.
The main thing I look for in SSD benchmarks are max latency, the Intel drives (even G1) still today are some of the best in that regards.. I think this is the best thing to look for in regards to fluidity.
Micron is good in max latency (I think the native Intel based drives G2 and newer still beat them though in max latency), and they have a well-tested and good quality assured controller in the M4s.
I wouldn't put money into anything other than Micron or Intel, they've got the engineering resources to do it right. I'm certainly no fanboy, I just found what you're seeing in my own drives. A Vertex 60GB makes a great drive to migrate to a laptop IMO.
I was so convinced by the experience of my 160GB G2 that I went ahead and sold my Vertex, and got a 40GB G2 to replace it. The Intel stuff gets beaten in benchmarks, but once you get your hands on one, I don't think you'll ever care to replace them no matter what new benchmarks say.
Though, I'm tempted to get a 256MB M4 myself.

I would do so if I had a good SATA6gb controller.. I have an aftermarket PCIE card, but I have a lot more faith in the latency and ops of ICH10R..
