well to answer your first question:
amd have created a naming system to identify their proccesors. the way they do this is buy comparing them to the intel proccesors
for example a
AMD 3700+ 64 means that compared to an intel it runs at 3.7 GHz but its true clock speed is 2.2GHz
now i no this seems a little comfusing but the reason that the true clock speed is lower is because AMD's move a larger chunk of information than the intels
intels move smaller bits of information quicker
AMD's move larger bits of information slower
but compared to each other the AMD's would really be running at 3.7 GHz
thats put simpily
so when you see AMD 64 4000+
just think ok so compared to an intel it would run at 4.0 Ghz but really it has a slower clock speed,
just in case you wanted to no the 64 infront of the speed is the type of proccesor it is
64 bits has twice the amount of pins that conect to the motherboard than a 32 but proccesor so it can procces twice the amount of information than a 32 bit processor
currently the AMD's are leading the feild by a long shot when it comes to 64 bit proccesors
but intels are far better at multimedia and multitasking
secondly,
according to graphics cards the amount of memory it has really isnt that much of a factor when it comes to performance the more memory it has the more breathing room it has to store its proccesed information
when measuring performance the best thing is to look for both memory clock and GPU clock,
the 7800 is just like a model number it has nothing to do with performance or anything it is purely an identifiying number
but yes a 7800 is a geforce branded card
1250MHz is the speed of the memory clock which would make it GDDR3 (graphics double data rate)
this determines how fast the information can be trasfered between the GPU and the memory
thirdly regarding HDD's
RPM 's is how fast the recording surfaces spin around under the recording head
the faster the disks rotate the faster information can be passed under the head of the hard drive,
cache is described here
http://www.vtec.co.u..._disk_cache.aspwell different numbers on the motherboard are for different things some times it can be jumpers or jumper settings
description of what goes where or what this connector is ( usaully abreviated )
but come on i cant tell you exectly what every little peice of writting says and what its for we could be here for hours lol
i hope this has helped a little bit and i hope it has been clear its late and im tired but never the less im always here to help,
