deadcell :
I see your situation completly now. I think you'r very limited in retail sources my friend, but I understand. I am just spoiled rotten here in the US. I looked at both systems specs and they are both good builts. The 4870 is realy not a garbage, its just that 2 of these didn't get me far. If the dx11 is out of your reach, so be it. As for the 920, I keep forgetting that you'r building 2 systems, and cost is a big factor here. The 920 adavanced in so many ways than my old i5-750, that I just kept recommending it to others. Again, you'r not getting it for a reasonable price, based on what you stated earlier, so I understand that too. Hope that you get these systems up and running with ease. Keep us updated...

I'm sorry deadcell, but I'm not entirely sure I follow you.
1. He is not limited to retail sources because he lives in Canada, as they have Newegg.ca, he is limited because he has a store credit.
2. He is only building one computer, just deciding between 2, so I'm not sure what you are really talking about with regard to that.
3. Also, didn't the i5s come out after the i7s?
4. What do you mean that two 4870s "didn't get you far"? You don't really go into depth about that, and Tom's rated the 4870 as a good buy at its price range:

So, as we don't know the absolute specifics about what the OP wants, saying "didn't get you far" doesn't really help unless you qualify it with the system you had and the games you were running. I just don't really see how your post will help the OP.
To the OP - Look at DND suggesting the 4890 with the i5. i5 is a great buy, and as overclocked shouldn't bottleneck most vid cards that you will be looking at, and probably into the future a bit as well. In terms of upgradability, either option should be fine, as has been discussed, and with Intel looking to (i think) i3s next year, the standards should hold up for a bit, and then prices of GPUs will come down as well.
With the two options, I think I would go with Option 1. Also, did you ever mention what resolution/monitor you will be using?
