Everyone I'm in a dilemma here so I'm going to be straight I'll supposed to save up my money and buy more memory for my Dell latitude D630 and it was an actual good idea, until one of the fan fins on my galaxy Geforce 550 Ti broke off when I was cleaning the fan of dust so now I have enough money to pay for one so we should be should be the memory for my laptop or the new heatsink for my video card? Let me know what you guys think I should do.

If you can find a computer store that accepts donated electronics and recycles/re-uses working pars, you could probably pick up both a heatsink AND ram for the price of just one otherwise. Granted, odds are they won't be brand spanking new, but they'll work just as well.

I don't know if there's a place called Free Geek in Maryland, but they're one of the businesses that does this.

Buying either a product computer store out of the question they might not have what i'm looking for.

Which is more affordable?

If you have a mode of transportation there and back, it wouldn't hurt to look. Worst case scenario, you don't find what you're looking for. Otherwise, you might find an equivalent or better of the parts you're looking for, possibly for cheaper.

One cost $21.20 $4.54 shipping, The other cost 19.99. However I do have shoprunner to get it here in 2-day free shipping.

Don't you have $50? Then you could get both.

Sorry I don't have $50 anyway I already made my choice I'm going with ARCTIC Accelero L2 Plus VGA Cooler - nVidia & AMD, 92mm Efficient PWM Fan, SLI/CrossFire.
