Not necessarily. It really depends on you having a 64-bit OS rather than a 32-bit one. If you have a 32-bit OS, you can expect your game to crash, not immediately, but sooner rather than later.
Besides, it could begin to get crowded in your 1GB video RAM (2x Crossfire does not count here, it is still only 1GB effectively) and that might start slowing you down. Still, I can't say for sure where the actual threshold for that might be, and it may also depend on your use of mods, etc. Also, I fear that 4GB of RAM may be on the low side if one wants to fully support a large number of HR textures.
If you have a 64-bit OS, you can go for it and see how it works out.
And by the the way, it is not \spolier but /spoiler.
P.S.
Oh, and this just came to mind: You can always "subscribe" to it and have it downloaded to your PC, as the actual decision to use it is made in the Data Files section of the game launcher by checking the boxes for the two esp files that accompany the textures. The only downside is, that if you end up not wanting to use it and attempt to delete the four DLC files (2x .esp + 2x .bsa, which take up a bit more than 3 GB of disk space), Steam will always insist on updating them for you unless you contact Valve directly to have the DLC removed from your account.
