when you've mentioned AMD as my cpu, honestly i was a little bit skeptical but as i read on, i guess i should consider it because of cores that it has for multi-tasking and other stuff. i can see that you've include a seagate as storage, what can you say about the brand? is that good compare to WD's caviar black? anyway, this is the best answer since you're the only on who answered it so far but i guess i should consider this as best option. thanks!
The Seagate Barracude and WD Caviar Blue are almost at the same level, the WD is said to be more reliable but none has the clear advantage over the other. So if you want something that is more reliable then go for Caviar Blue, it is just a few dollars more.
Also if you can extend your budget and get the WD Caviar Black, then it should be awesome, but the price of a WD Caviar Black is somewhat high, that is why i suggest you to do your own research and go for The Seagate Barracuda or the WD Caviar Blue. Go for whatever you find good.
@Sangeet i forgot to ask what can you say about the Gigabyte motherboard? is it okay compare to others specially Asus and MSI in terms of pairing with AMD cpu amd and overclocking? thanks!
The reason that i selected the Gigabyte UD3 motherboard, because it has an advantage over every other motherboard at that price range and that is that this motherboard has got a very good 8+2 phase VRM (Voltage Regulator Module), which is what I or anyone with knowledge of Overclocking would prefer over the other motherboards with relatively poor VRMs. That is why i selected this motherboard, as it is a beast in overclocking.
Hence you can ensure that your motherboard won't burn out when you would overclock it to like 5 Ghz. So this motherboard should be good for everything. Just get it. It would not be a problem because the quality of this motherboard is very good.
If you think that the answer helped, then don't forget to select it as the best answer. It would be highly appreciated by me.
