Sigh.
1. I gave EXAMPLES. I have explained this already. Just because I list some examples, that doesn't mean that's it. A list of EXAMPLES means, a few out of many. I am just listing some that come to mind that I know are demanding.
I don't know what is more demanding as it's very difficult to tell with games sometimes. For EXAMPLE, my current laptop can run Castlevania 2 on Medium graphics which looks amazing, but it cannot run Resident Evil 4 HD on lowest settings, yet Castlevania is much more graphically impressive than RE4HD. I don't understand why it runs Castlevania but not RE4HD.
2. I think the point that you're saying that it's the biggest OUT is pointless, as I have already stated, I am wanting to prepare for future releases. Why purchase a £250 graphics card that is just enough to run current titles, when you will potentially be required to go and purchase a £350 card to play some new titles within the next year? Why not just save £250 and purchase the £350 from the beginning if you can afford to?
3. There's no such thing as overkill, unless I was to say I was only planning on playing The Stick Of Truth... or Fallout 1. I am playing demanding titles, therefore having some extra power is going to mean my PC is able to handle it easier, and therefore not get as heated, and generally just perform better.
In conclusion, I am purchasing the system I wish to purchase that I am able to afford, I am asking advice on the components regarding compatibility and quality, and suggestions for any better components and reasons why. I am not asking for someone to tell me to downgrade because they cannot comprehend that I am purchasing a graphics card slightly better than I need right now, as I wish to be able to just play future titles and not be required to buy yet another card.
