Hard drive + GPU + ram upgrade

Hey I am running a i7 720QM + 260M GTX + 4 GBRAM + 7200 (or 5400 forgot) 250GB. 2 years old.

I am tihnking of upgrading my RAM to a) two 4-GBs 1600 or 1333 doesnt matter; b) an SSD 128GB upgrade or something with express cache config; c) some decent graphics upgrade (want more performance; same or lower power consumption).

I am prepared to pay for a 6990M or 570M but it depends on what my local store will sell me. (based in HK; we might have cheaper Taiwan cards)

So my questions:

1) my problem with hard drives - its not well documented here what kind of SSD will work. If someone could explain to me how trad. HDD (like 500G) + express cache (32GB) works incomparison with full SSD drives, that would be great. (weight, speed, price)

2) Also, there isn't any discussion on how today's newer 650M, 660M will fare on our M15X.

3) RAM should be very easy.

Thank you in advance.

 

keep in mind the M15X is an older machine, not as new as m17xr3 etc....
so dont expect any new hardware to be "plug and play " if you understand what im saying.

but try and get a dell 6970m gpu, the i7 720qm should be just fine if u not into heavy encoding etc...
i would just keep the 500gig hard drive for now, its probably 7200rpm anyways, so would be just fine until ssd prices are better etc.

 

Today I checked with my local vendor - I could get an OCZ 128G SSD for $90 USD. I tihnk it is a very good price.

Lol 4GB 1333 are 23 USD here.

WIll check the graphic cards later today after work.

Thanks.

Do let me know if you have information on upgrading to 650M+.
