Ok I'm looking at reviving an old system and have finally gotten down to fine tuning it. What I am asking is the 5800+ better or even on par with the 6000+. I have a HP Pavilion A1540N and I found out that the 5800+ was made specifically for HP computers, but at the same time while they are rated at the same speeds, would the 6000+ with an L2 cache of 1MB be more helpful than the 512 of the 5800+. Unless the 5800+ has much better performance than the 6000+ I'm thinking of sticking to the 6000+ due to price. So to put it simply, Which one gives me more bang for my buck.
I couldn't tell you which is the better bang for the buck as the circumstances of your purchase are not entirely clear from your post.
I do not think the 5800 was made specifically for HP. It was available as a retail unit, if I remember correctly.
There is little speed difference between the 5800 and 6000. The 6000 is faster, but only slightly.
