Extra swap room = more disk thrashing. Not something you really want.

Also, some bits to keep in mind:

• Windows Vista is pure crap for memory management. Downgrade to XP or bump it to Windows 7 (well, if you can get hold of the Release Candidate or have EA/SA license access, otherwise you get to wait until October 22nd for that option).

* Not all parts behave well together. If your computer is a home-built put together from odd or spare parts, and the RAM, HDD's, etc weren't exactly made to run well on your mobo? Bad Mojo, no matter what the CPU specs are. OEM machines (HP, Dell, etc) aren't much better, since they have a nasty habit of using grey-market parts or "house brand" parts that barely meet their stated specs. It also hurts when OEMs pack crapware onto the box (Even straight-from-HP printer drivers will suck down CPU cycles, just to bug you to buy ink cartridges and such every time you print something).

* Your best bet is to carefully shop for and build a machine with all the parts made for one another. Tom's Hardware, hexus.net, and the like are good places to start for making comparisons and matching specs.

* Go download a copy of CCleaner (it's free) and use the hell out of it. It lets you clear out the startup crap, cleans your registry, and flushes your web caches enough to speed up damned near any web browser.

* Defrag, defrag, defrag, defrag. Don't bother with the built-in tool either - go get JKDefrag (also free) and turn it loose. The first run will take an hour or more (prolly more), but subsequent runs will be fast, and your computer will speed up because of it (disk seek times shrink, etc).

HTH a bit.
