The 9xx series have 4MB of cache, while the 8xx series has only 2MB.
The 8xx series are lower-end and less produyctive than the 9xx series. Like nVidia, for example, a GeForce 6800 is better than a GeForce 6600.
The 9xx series has a potentially better core, and should be able to achieve higher clock speeds. If, however, you were to buy one for a budget PC, I would buy the 8xx series with a decent motherboard. You NEVER want a budget motherboard. Trust me, I did this and I am not proud of it. For example:
You need a budget CPU and motherboard. Your budget is about $325. You would either buy A:
Pentium 4 920 - http://www.newegg.com/Product/Produc...82E16819116237
Asus P5VD1-X - http://www.newegg.com/Product/Produc...82E16813131566
Total: $320.34 (w/shipping)
Pentium 4 820 - http://www.newegg.com/Product/Produc...82E16819116213
Asus P5GD1-VM - http://www.newegg.com/Product/Produc...82E16813131520
Total: $316.49 (w/shipping)
Option B would be the best choice on a budget, because the more expensive motherboard offers more upgradability. It also has much better chipsets than the lower end one. You would also be more likely to sell option B easier than A, due to the much better motherboard. Like my board. If I was to buy a Duron 1.8 and a nf7-s2, I would have a better computer for less money.
