| If you have A ... | The best Upgrade is.. | Why? | Total Cost | 
| 486 | Buy a whole New computer | Computers are so much more advanced now, upgrade options
for 486 systems are slim and probably will not give you the performance
boost you are looking for. | $500+ Low End $1,000 - $1,500
 $1,500 High End
 | 
| Pentium (any speed with 16MB RAM) | Buy at least 16MB of additional RAM | Todays programs are requiring more and more RAM. 
I recommend you have at least 32 MB of RAM more if you can afford it. | $25 - $60 | 
| Pentium (any speed with 1 or 2 MB 2D Video card) | Buy at least a 4MB Video card | You will get significant improvment in your video speed
by upgrading your video card.  Add a 3D accelerator if you play lots
of 3D video games. | 2D $25-$200 2D/3D $50 -$200
 3D $75-$200
 | 
| Pentium (any speed with no hard drive space left) | Buy a new Hard Drive | If you buy a big enough hard drive you may never have
to upgrade this part again.  You can also transfer this part to a
new system if you decide to buy a new system down the road. | $120-$200 depending on size | 
| PB 640 Motherboard (with no L2 cache) | Add L2 cache if you have a COAST socket | 212k will increase your systems performance by 24%, 512k
will add another 4% increase. | $20-$40 | 
| Pentium-60 Systems | Buy PowerLeap PL-54CMMX-233 Adapter with an Intel 233
MMX processor | This upgrade can bring your system up to 210 or 233 MHz
depending on max bus speed. | $199.95 | 
| Socket 5 Pentium-75 to 133 Pentium Systems | PL-ProMMX-233 Intel MMX | This upgrade can bring your system up to 233 MHz depending
on max bus speed. An IDT Winchip can also be used with out a BIOS upgrade
and it cost a lot less. | $179 | 
| OR | 
| PL-ProMMX AMD K6-2 | This upgrade can bring your system up to 333 MHz and
maybe even 400 MHz.  The BIOS upgrade can be tricky but it is well
worth it. | $179 - $249 + $40- $80 for the BIOS
 | 
| Socket 5 and Socket 7 Pentium-75 to 233 Pentium Systems
with a BIOS that Supports AMD processors (PB 600) | PL-ProMMX AMD K6-2 | This upgrade can bring your system up to 333 MHz and
maybe even 400 MHz.  Without the L2 cache this is still a good upgrade,
however performance will be cut a bit. | $179 - $249 | 
| All other Socket 7 Pentium-75 to 233 Pentium
Systems | PL-ProMMX-233 Intel MMX | This upgrade can bring your system up to 233 MHz depending
on max bus speed.  An IDT Winchip can also be used with out a BIOS
upgrade and it cost a lot less. | $179 | 
| OR | 
| PL-ProMMX AMD K6-2 | This upgrade can bring your system up to 333 MHz and
maybe even 400 MHz.  The BIOS upgrade can be tricky but it is well
worth it. | $179 - $249 + $40- $80 for the BIOS
 | 
| All System that are > 233 MHz or more should have sufficient
power for todays applications and probably don't need a CPU at the time
of this writting . |
