As in last year's game, expect to encounter dense jungle environments, barren ice fields, Korean soldiers and plenty of flying aliens. There's no denying that this is more of the same, except here it's a more tightly woven experience with a little less freedom to explore.

With a top-end PC (although Warhead has supposedly benefited from an improved game engine, you'll still need a fairly beefy system) rest assured, developer Crytek has enhanced more than just the graphics engine.

Vehicles are more fun to drive, firefights are more intense and focused, and aliens do more than just float around you. More emphasis on the open-ended environments would have been welcome, but a more exciting (though shorter) campaign, a new multiplayer mode, and a whole bunch of new maps make Crysis Warhead an excellent expansion to one of last year's best shooters.

Crysis Warhead has good looks. As mentioned before, the game looks better than Crysis, and it runs better too. Our test machine that struggled a bit to run the original at high settings ran Warhead smoothly with the same settings. Yet as much as you may have heard about Crysis' technical prowess, you'll still be impressed when you feast your eyes on the swaying vegetation, surging water, and expressive animations. Outstanding graphics. Couldn't say more here.

We up the ante a little more by enabling DX10. Though we really wanted to push 4x AA here, we notice that current day graphics cards yet again run out of memory once they reach the highest resolutions, the result is HDD activity going up a lot affecting the framerate dramatically, disallowing an objective measurement of our time demo.

So 2x AA in combo with the gamers quality mode is what we test at, which looks sparkling to be honest, but a budget card will have it rough, really rough.

• Level Ambush
• Codepath DX10
• Anti-Aliasing 2x MSAA
• In game Quality mode Gamer

Of course if you disable AA to get better framerates, the overclock will kick in just as nicely, but again that's roughly 15~20% extra performance on the fly.

Fallout 3

You know, it’s been a decade since the last Fallout release, and a lot has happened since then. Fallout 3 takes place roughly two-hundred years after a nuclear war devastated the planet. While the series originally started in Southern California, this time around you’ll find yourself in a post-apocalyptic Washington D.C., better known as the Capital Wasteland. You are a resident of Vault 101, one of a series of fallout vaults built to protect its inhabitants from the harsh conditions in the wasteland. As the story goes, in Vault 101, nobody enters - and nobody leaves. Raised as a child in the vault, the game begins with you as a young lad learning to take your first steps and continues as you grow older (this portion of the game is used as both a training mission and to build an affinity with your character). It isn’t until you wake up one day to find the vault in chaos - your father has somehow left and it’s up to you to follow him into the wasteland - where the story really begins.

Fallout 3 is an immersive, graphically stunning title with that awesome movie feel. Easily one of the best games of 2008, a must buy Gurus... a must buy.

Fallout 3 is again a title that really digs this overclock. Sure at 2560x1600 we are flat-out GPU and Video memory limited, but again at say 1600x1200 we see a ~17% performance increase.
