There are some pretty decently priced cpu's from AMD, which according to most experts, are only second to Macs as far as graphics are concerned. If renders are floating coma operations, then Intel is best, but you should go for an i7, with its inflated price tag.
I won't argue with you about cpu's, since I'm an AMD fan, with some long experience with them.
I'm very sorry to learn about your problems, and understand you very well. The same policies were applied in Argentina during the 90's, and ended up violently late in 2001. Since 2003, this has changed and the country, with many difficulties though, is recovering. Now we face a condemn from the freaking financial world that rules everything, because we are a "bad example" for the rest of the world. How is it that a country going against the current is doing well. The disease should not spread, bad for business!
Deeply hope you and your beautiful country all the best.
we know the Argentina's issues,very well! it was the begining of the new Order of things,i think! unfortunately,the banks and the speculators and the shylocks will prevail. thank you for the wishes,dear!
