Cpu cooling help with decision

I asked this question earlier but I am in the market for picking up a new cpu cooler for my computer. The processor is going to be upgraded eventually so I'm looking for a lasting cooler that I can use for OC'ing in the future.

gb 990fx ud3 mobo
Tempest 210 case (5 fans. 2 top exhaust. 1 rear Ex. 2 front intake)
Athlon x4 645

I have around $60 dollar budget and am deciding between the antec 620 kit

or Spire eclipse II

I had originally bought a Corsair A70 and it ended up being a disaster as it did not clear my case at all and was MM's off (possibly a 1/4 inch) being 159.5mm so I ended up returning it.

After looking at reviews on the coolers I'm leaning towards the Spire cooler but am concerned that 152mm might not be that much of a difference from the A70 159.5mm and won't fit in my case.

The antec kit is appealing since I would end up slightly less and I do not need to worry about clearance for my case.

Any thoughts or suggestions? Thanks

Oh and davcon I thank you earlier for your help.
