At the time i bought the deluxe jimbo, it was the top end model in the ddr2 section, there was a p5q3 that used ddr3. But it wasnt a popular board. The deluxe was closely followed by the p5qe, main differences were better power phase on the deluxe, a few extra sata ports and a bigger heatpipe assembly iirc and x2 ethernet ports. Both were excellent boards, the p5q pro turbo came out a bit later, but still an excellent board as pastymuncher has mentioned. The se was a mediocre one tbh, as said, extremely poor layout. If you look about, you could pick up the deluxe for very little money, iirc i sold my deluxe just over 3 years ago for £70.00 to fund an upgrade to x58. Should be much cheaper now. Arguably the best overclocking board ive ever owned.
