Hmm. Being so borderline on the hardware, you might indeed run into a few problems. Maybe not exactly showstoppers - you might for instance have to start freezing synths etc.
I notice you're also running Windows 7 in 32 bit mode - this automatically means you won't be able to make use of the full 4Gb of RAM you have installed, it will be restricted to a little over 3Gb, so that's another performance hit.
But, do as Vinny has suggested - download & install the trial version and see how you get on.
You'll be much better placed to make an informed decision.
