Few quick Qs - HD, RAM, B-G vs. A-B-G

OK tell me the pros and cons of each and which one to pick..........o yeah Please

5400rmp (2MB Buffer) - 7200rpm (8MB buffer) ? better (common sense tell me that 7200 rmp is better, but Is it worth giving up space since the 7200 comes in smaller capacities?

Difference between (both 512MB DDR2 SDRAM) 1 DIMM and 2 DIMM? which one?

Is it worth it to get a wireless adapter with all three (a,b,g) or is the major ones ok (b,g)? when would I use wireless 802.11a???

Making sure, when talking about vid. card, the VRAM is the dedicated RAM on the card so it doesn't have to "share" the system RAM right?

 

7200 rpm is better, you can get very large 7200rpm drives nowadays so space isnt an issue.

not sure what the 2nd Q means.

you only need B & G, A is obsolete.

correct, although in your bios is a setting called "graphics aperture". that is how much RAM your video card is permitted to use, if it so wishes to.

 

There is an option for 1 DIMM or 2 DIMM for the RAM. What is this difference? what does DIMM mean again...i seem to always forget. for the HD, is there a noticeable difference?????

 

I think that's just the different slots on the mobo.

 

Ok, that makes sense.......i've been busy with exams, and my mind is being "overclocked"

 

Actually A is not obsolete, it is a newer format for WiFi. 802.11a was introduced in 2002. http://www.pcworld.com/news/article/0,aid,77544,00.asp

802.11b is obsolete.

 

can the difference be seen/felt between 5400 2MB and 7200 8MB HDs?????

 

Actually yes there is a difference between 5400 and 7200 speed drives, and along with the cache of the drive. The larger the buffer, the better the transfer rates. The buffer is actually on the platters of the harddrive. Mine is a 60gb, but WinXP and Linux only see 55.8, because of the buffer.
