the only bad thing regarding the Giga-byte GA-8IRXP i have seen so far is that it is not a very good overclocking board but stability wise, it is the best.
on toms hardware, they were able to push the board to 3.0Ghz (i think it was 2.0a or was it 2.2a ?). Anandtech also gave this board high remarks. I think that i will go with the 8IRXP board. Since it has all the features that i want. I am not looking into pushing my processor to 2.4Ghz and above. Looking somewhere around 2.1-2.2Ghz (that should be 2200/16 = ~137FSB. if i am able to do ~135 (133 - 137 fsb), i am satisfied, i dont need 150 fsb. considering usb2.0, raid and dual bios, onboard nic, i think that i will go with giga-byte beacause of high stability and features.
i really dont want to go with SIS chipset, again the stability issue again. I am an Intel fan so far and i guess that i will remain to be one. So SIS chipset is outta question for me, so with only 845 chipset, i think that giga-byte will be the best. I have lots of USB devices so cant afford to have those messed up with P4266 board, also would hate to spend extra $10-$10 for nic card for MSI, so giga-byte it is
finally a decision is made unless someone gives me strong reasons again to switch to some other mobo design.
here are my final system specs as of now:
Antec SX1030 case w/ 300w psu
Giga-byte GA-8IRXP mobo
Intel P4 1.6A retail processor
Samsung DDR PC 2100 256 mb chip + Samsung DDR PC 2100 128 mb chip (total 384 mb)
Visiontek GeForce 3 TI 200 w/ 64 mb DDR ram video card
Maxtor DiamondPlus 46GB 7200 rpm Hard Drive
SB Live Sound card
Lite-on 16x DVD-Rom drive
Lite-on 24x CD-RW drive
i am little skeptical about the samsung DDR memory. is samsung good for overclocking ? i know, i know, Crucial is the best but.......i already have Samsung chips. might switch to Crucial later on
Thanks to all that have helped in giving me some feedback.
