the i5 is much better than the phenom ii x4. i see you are on a budget. thats why i suggested the amd.
you have to determine which cpu you want. no one else can since there are people that stick with one and not the other or there some that go by specs. so do some research on the cpu's of your choices! okay?
and as for the ram both have the same specs. the one i chose has many good user rieviews. so i thought of choosing em!
lower CAS timings are better, but please note that the actual difference in performance will be negligible in real life. You will not be able to tell any difference in performance, when the sticks are used in otherwise identical machines.
If the price difference is more than $50, go with the slower timings. If they are the same price, than go for the lower timing memory.
The gigabyte UD3 is the only one that is really worth and that is only worth it if you buy in a combo with the CPU gigabyte isn't rocking this new-gen asrock is beating it's budget boards and asus it's high-ends.
the UD3 doesn't support CF/SLI one good card will be enough for up to 1920x1080 though
Any gigabyte boards you would recommend? Also I am pretty tempted on getting a board with uefi bios what are your thoughts on this?
If you want to run dual vid cards with a Gigabyte board then you need to look at the UD4 seeing ho it's the cheapest of the Gigabyte P67 boards that run two cards that run dual cards @ 8x & 8x. That board goes for $190 at newegg. You could save yourself $40 and go with the Asrock extreme4. That board got great reviews btw.
