Which one is better?

AMD or INTEL;)

I think both of them are good why?

If u don't want spend lot of money for your pc AMD is a good choice and if u want the best INTEL and NVIDIA is your choice but what is the difference?

In my opinion the truth is there is no big difference just wasting the money the cheaper one is suitable for someone need money;)

but if the money is not important for someone NVIDIA and INTEL are the best choice.

Here is my offer for buying a new pc:

1-AMD

1-AMD phenom 2 955 black edition

2-ATI 4870x2 or 4890 or 4850 or 4850x2

3-Famous Motherboard compatible with AMD Phenom 2 like GIGABYTE[GA-MA790FXT-UDP5]

2-INTEL&NVIDIA

1-INTEL i7 965 extreme

2-NVIDIA GTX 295 or GTX 285 or GTX 275 or GTX 260

3-Famous Motherboard compatible with INTEL i7 like GIGABYTE[GA-EX58-EXTREME]

What manufacture is better?

I think GIGABYTE and ASUS and MSI and XFX are the best but i prefer the GIGABYTE because it has better technology for example ultra durable 3 has better technology.
