New graphics cards and HDD

[Furunculus]

I just want to remind you that the 64GB version of any SSD is slower than the 128GB version of that same SSD, most likely because it can do more things parallel when an SSD is bigger. More space also increases the lifetime in write cycles, ones made in smaller nanometer structures also live shorter (they work by transferring electrons through some kind of insulation and the more often they do it, the more that insulation gets damaged until it fails, which is when that particular cell cannot be written into anymore, so more cells and thicker "walls" = better).
I wouldn't get one below 120 or 250GB anyway as I always manage to clog my C-partition somehow.

Concerning the graphics card, if that asus has 2GB RAM, then maybe take that, otherwise take the cheapest one with the features you want (do you need HDMI for example?) Anything that doesn't have a custom cooler or isn't overclocked is usually just the reference design anyway, regardless of which manufacturer it's from. Whether they have a good and fast customer service might be another consideration.

can depend on the model, with the Crucial Real SSD the write speed on smaller drives is much slower, but the read speed remains the same, so it makes for a good boot driver rather than an apps drive, which is what the Samsung F3 is for. not sure how the sandforce drives behave in the same circumstance.

about the vid-card - agreed.
