but I would think the easiest..and cheapest way is just to find a motherboard that matches your ram...there may be some markings on your ram to signify what it is...and hopefully all the same?
this is just for reference:
800 Euro = 1,255.69 US Dollar
prices in US
cpu - $231
Newegg.com - Intel Core 2 Duo E6600 Conroe 2.4GHz 4M shared L2 Cache LGA 775 65W Dual-Core Processor - Retail
motherboard - $95
Newegg.com - Intel BLKDP965LTCK LGA 775 Intel P965 Express ATX Intel Motherboard - OEM
the only catch is I'm picking something not knowing what your ram is
your clavier is your keyboard eh?
and you would have a lot left over for gpu...graphics card...go with nvidia
if your ram is too old for the newer hardware, maybe get new ram, still would be very affordable given what you have....but then I say don't spend it all...only about half or 75% and SAVE!
