Ello trouble, just shooting off from work but
Pentiums are better. The info is below but you'll prob just take my word for it

# Core - The Celeron chip is based on a Pentium 4 core.
# Cache - Celeron chips have less cache memory than Pentium 4 chips do. A Celeron might have 128 kilobytes of L2 cache, while a Pentium 4 can have four times that. The amount of L2 cache memory can have a big effect on performance.
# Clock speed - Intel manufactures the Pentium 4 chips to run at a higher clock speed than Celeron chips. The fastest Pentium 4 might be 60 percent faster than the fastest Celeron.
# Bus speed - There are differences in the maximum bus speeds that the processors allow. Pentium 4s tend to be about 30 percent faster than Celerons.
