how fast is a 040 cpu?

The 68030 CPU board has the same memory issues and an A3640 will be noticibly faster--around the 4x per clock cycle, as previously said. A CPU card with onboard memory will speed up things a lot more due to faster memory access. The fastest accellerators are the Phase 5 cyberstorms but they are spendy. Warp Engines are a good alternative and usually sell for quite a bit less. If you get a chance to get an A3640 for $100 or less, I would get it. My A4000 was noticbly faster with a stock 3640 25mhz CPU than my 68030 A2500 with a DKB 2630 memory expansion. Sysinfo will tell you how fast your system is in reference to other systems:

I have had a couple of GVP T-Rexes and they aren't bad in build quality but the custom simms and almost impossible to get additional memory board are what really limit them. The T-Rex II has SCSI and standard Simm sockets and would be a good bet but they are fairly rare compared to the Warp Engine and Phase 5 boards.

I have had a look on cpu on ebay. can it be true that a 68060 cpu with 128 mb ram cost 800 dollars?

Sounds like a lot for a Cyberstorm MK3 but the Cyberstorm PPC often sells for that or much  more. Ebay prices fluctuate wildly. There were a couple of Warp engines that went for under $200 last winter and a couple that sold for around $400 a few months ago. For an 060 CPU card, the price seems to be around $400-500 with some sellers wanting more. I just checked the current listings for Amiga accelerators and there is only one 060--a phase 5 blizzard for the A2000. The seller wants $600 and its been listed for a while. It would probably sell quickly for $300-$400.

You can often find much better deals on forums but be careful to check a bit on the seller. If it's someone with only a couple of posts, it's risky. If it's an established member with years of posting, usually good. I got my Cyberstorm PPC from a private contact--another old Amigan--who did a lot of serious work with Amigas back in the day. The price was much less than what I would have paid on eBay.
