well dtuck, truthfully if you can wait, wait for Dell to have a price drop on the c2d. The core duo is great, but newer processors are always better. You'll have to ask someone who's actually tested both. Maybe check out some benchmarks...
Have you tried playing around with the m1210 or equivalent sized keyboard? It is the decision killer for many people. I'd go with the E1505 since you said you want to game a little. Plus it's a little cheaper than the m1210.

Less pipelines and theoretical fill rates....
