Intel is still king in terms of performance, but the
AMD's Phenom II series is still okay (i assume Phenom II since the first Phenom can barely do 3Ghz and is very slow). Also, 4GB GDDR5 for desktop does not exist, GDDR5 is only for graphics cards (hence Graphics Double Data rate memory). DDR3 is the only memory module available for desktop computing for now.
Anyway, also made some quo...i used the newer i5 Quad core series instead (i5 sandybridge instead of the old i7 nehalem), Most games doesn't really take much advantage of the Hyper threading capabilities of the i7 based on the benchies.

And these new sandy bridge processors can easily pass beyond 4Ghz when overclocked (~4.8 to 5Ghz)

(prices is based from PCHUB gilmore)
This should play most newer games at very high settings at 1080p (MMO games eats less resources and at this spec, its already overkill)
Monitor and casing can be subjective, minsan nasa tao na yun, but preferrably a LED monitor with 1080p capability and full tower na casing ang recommended so its not the final price.
For the Video Card, you can also opt for the Sapphire Radeon HD 6970 2GB GDDR5 which is similar in price and performance to the GTX 570. If you don't care for nVidia CUDA, PhysX and better compute performance go for AMD, otherwise, take the nVidia route.
