It should be ok, the L2 for Chess makes next to no difference. If you'd like to compare take a Duron vs a Thunderbird. The only difference is the Duron has 64k L2 where as the Thunderbird has 256K L2. If you're comparing against the new Duron (morgan) you should compare with the AthlonXP instead, as the new duron has some extra enhancements (like better prefetch).
